▼ This thesis presents a comparative study between two silver nanoparticle inks that were deposited using a Drop-on-Demand (DoD) inkjet printer, aiming at finding a functional ink that can be used to print electrodes in Light-emitting Electrochemical Cells (LECs). To achieve this, a DoD inkjet printer was installed and an acquaintance with the printer was attained. Among the two inks, one was employed as received while the other was reformulated, and successful deposition of both the inks was observed. During the reformulation process, it was seen that the highly volatile tetrahydrofuran (THF) solvent can be used to improve the ink properties, in contrast to what is recommended. After that, the inks were deposited on UV-ozone treated glass substrates, sintered at an elevated temperature under ambient conditions, and their specific resistances and thicknesses were measured. Finally, the inks were used to print the anode in a structured sandwich-cell LEC. The performance comparison was conducted by observing the emitted light of the LECs. The results indicate that the reformulated ink performs better, probably due to the lower silver concentration that results in flatter surface, which in turn effectively alleviates shorts.

▼ Isotropically conductive adhesives (ICAs) and inks are potential candidates for low cost interconnect materials and widely used in electrical/electronic packaging applications. Silver (Ag)filled ICAs and inks are the most popular due to their high conductivity and good reliability. However, the price of Ag is a significant issue for the wider exploitation of these materials in low cost, high volume applications such as printed electronics. In addition, there is a need to develop systems compatible with temperature sensitive substrates through the use of alternative materials and heating methods. Copper (Cu) is considered as a more cost-effective filler for ICAs and in this work, Cu powders were treated to remove the oxide layer and then protected with a self-assembled monolayer (SAM). The coating was found to be able to limit the re-oxidation of the Cumicron particles. The treated Cu powderswerecombined with one of two different adhesive resins to form ICAs that were stencil printed onto glass substrates before curing. The use of conventional and microwave assisted heating methods under an inert atmosphere for the curing of the Cu loaded ICAs was investigated in detail. The samples were characterised for electrical performance, microstructure and shrinkage as a function of curing temperature (80-150°C) and time. Tracks with electrical conductivity comparable to Ag filled adhesives were obtained for both curing methods and with both resins. It was found that curing could be accelerated and/or carried out at lower temperature with the addition of microwave radiation for one adhesive resin, but the other showed almost no absorption indicating a difference in curing mechanism for the two formulations.

▼ The present paper discusses the application of the silicon-aluminum and its chemical compound thin film applied on non
conductive vacuum metallization (NCVM) and passivation layer of the a-IGZO thin-film transistors (a-IGZO TFTs). The first part of the paper compares the advantages of the liquid phase process and solid phase process in preparing silicon-aluminum target, and tries to establish a mass production technique with uniform texture. The second part uses the silicon-aluminum target to investigate the optical and electrical properties of silicon-aluminum thin film. The third part focuses on reactive sputtering technique, deposits silicon-aluminum nitric oxide (SiAlNO) thin film, and studies the effect and mechanism of improving the ambient atmosphere stability of the a-IGZO TFTs.
The research firstly produces target of which shrinkage and macro segregation defects are significantly reduced by the mould designed and of casting parameter controlled; however, the micro segregation and coarse casting texture still affect the thin film quality during sputtering test. Due to the poor wetting property of liquid aluminum and silicon, either infiltration method or liquid-phase sintering method can reach the 99% theoretical density standard for sputtering target. Hot press process can obtain silicon-aluminum alloy with better density, micro structural and uniform texture via proper adjustment of parameters, but the process window is limited and not available to mass production. Silicon-aluminum target made by hot isostatic pressing process has surpassed the casting and hot press process not only on density, but also the consistency of microstructure as well. It successively established silicon-aluminum target production technique capable of mass production, and effectively improved consistency of sputtering thin film in the composition and structure.
In development of the thin film with high reflectivity and high resistance, the research attempts to develop a new NCVM film based on the opinion of metal
nano particles distributed on non-
conductive substrate. A dual-phase microstructure composed of
nano-sized Al particles dispersed in an amorphous Si matrix was obtained which is different from the solid solution amorphous structure of traditional co-sputtering. When the aluminum content is at 15-30%, and the thickness of silicon-aluminum thin film with a range of 20-50nm, its sheet resistance can reach 106 Ωï¼â¡, also reflectivity of the visible light is over 60%, which comply with the NCVM requirements. In theoretical calculation, EMA is only applicable for metallic character, i.e. silicon-alumium thin film of which alumium content is larger than percolation threshold, within this range, the simulation result is quite similar to the experimental result.
The research extends the silicon-aluminum target application from NCVM to the passivation layer of a-IGZO TFTs, and finds out the deposited SiAlNO thin film produced by the sputtering process not only can protect the a-IGZO from being affected by the oxygen and moisture…

▼ The natural world has many superhydrophobic and self-cleaning surfaces such as butterfly wings and lotus plant leaves, both well known examples of self-cleaning surfaces. Water droplets on these surfaces can pick up dirt particles and remove contamination. The significant self-cleaning ability of these surfaces has inspired many researchers to attempt to fabricate these superhydrophobic coatings, mimicking their self-cleaning properties, using different methods. Most of the superhydrophobic coatings described in current literature need to be cured in ovens and thus difficult to be applied and/or be maintained in the work place. Therefore, there is a need to develop room temperature curing superhydrophobic coatings using simple and inexpensive processes. This study demonstrates the fabrication of room temperature superhydrophobic coatings by using RTV (Room Temperature Vulcanizing) silicone rubber and fluoropolyurethane polymers. Also the effects of various parameters such as resin and solvent type, additives, coatings thickness and production methods, on the properties of superhydrophobic coatings, were evaluated. The final coatings showed contact angles higher than 145º and good UV and water durability. In addition, the superhydrophobic RTV silicone rubber coatings passed the erosion and track resistance test, a major test for high voltage insulator coatings in the industry.Conductive coatings are used in a variety of applications such as antistatic surfaces, electromagnetic interference shielding (EMI) and sensors. Despite previous research, most conductive coatings in the market that have high conductivity are made from metallic conductive fillers that are expensive and need to be compounded with polymers in high concentrations. Also, conductive mesh coatings used in the market require a complex process and should be prepared with some different processing steps. This project focuses on conductive coatings and mesh coatings that show good conductivity and have low cost. The results indicated that nano clay could improve the electrical and mechanical properties of conductive coatings. Also, conductive mesh coatings prepared by emulsion method could be a good candidate to make simple and cheap mesh coatings for electromagnetic shielding.

Modification of Water Uptake Capacity of Wood Using Colloidal Solution by Impregnation Technique.

▼ Hygroscopic properties are important characteristics of a material that is used in building
construction. Wood is an anisotropic, heterogeneous and hygroscopic material. Given the
cellular structure of wood as well as capillary action in the Lumina, the level of water uptake
in wood is significant.
Such amount of water uptake makes the wood susceptible to dimensional instabilities, causes
alterations in the mechanical properties, and potential for degradation of the material. Various
approaches have been investigated to modify the hydrophilic nature of lignocellulosic
materials, including surface modifications using silane treatments, acetylation, wax etc.
Although these surface modifications can decrease the rate of water uptake by the materials,
the amount of water uptake at saturation remains unchanged. In fact, the lumen diameter is so
small that the rise of liquid, even with a hydrophobic surface, can still occur. Therefore, the
only way to halt the water uptake driven by capillary action in lignocellulosic materials is to
apply a uniform cover on the material surface in addition to filling the lumen with dense
material.
In the current research project, the vascular structure of softwood (Spruce) is obstructed by
silica nanoparticles using the impregnation technique as one of the advanced methods to
reduce the water absorption capacity in wood. This process can form a thin film of
nanoparticles on solid objects with complex geometries. In addition, the technique can fill up
the cavities and voids of porous materials and prevent the capillary action inside the Lumina.
In this method, the wood specimen is dipped into the solution, silica 40 (wt. %) colloidal
solution. Then the solvent is evaporated which results in the formation of nanoparticles in
the form of thin films or particulates. The former may change the moisture absorption on the
surface and the later reduces the capillarity of the vascular system. This project aims to find
the optimal impregnation condition to minimize the water uptake capacity of wood in order to
increase wood physical and mechanical stabilities.
Three immersing times (i.e. short, medium, and long) were used to coat wooden samples with
the silica colloidal solution. The samples were conditioned in wet environments with specificiii
relative time and then their weight as percentage change were examined. To investigate the
capability of the method to obstruct the vascular structure of the wood samples, the
characteristic process was done in the next step by some common tests such as X-ray
Diffraction (XRD), Scanning Electron Microscope (SEM), Water Contact Angle (WCA), etc.
The results from the experiments show that dip-coating the wood samples with silica
nanoparticle colloidal solution had effect on the amount of water absorption, but significant
levels of reduction in water attraction was achieved with considering the other effective
parameters such as duration of each set, the number of sets that are conducted, and
impregnation in vacuumed condition.…

▼ This research focuses on the investigation of Earth abundant copper and carbon based nanomaterials that are subjected to Intense Pulsed Light Processing to create
conductive films, as future flexible electronics and renewable energy solutions would benefit from the quick and scalable production of
conductive films. Use of nanomaterials in their oxide/hydroxide forms leads to higher stability in aqueous
inks for efficient large area solution deposition. IPL Processing utilized 2044 μs pulses ranging from 589 J - 2070 J over an area of 1.9 cm x 30.5 cm, with energy densities of 10.1, 12.8, 15.8, 19.2, 22.9, 26.8, 31.1 and 35.7 Jcm
-2, of non-coherent white light in wavelengths ranging from UV to NIR (240 nm – 1,000 nm) through a xenon lamp. The rapid pulses induce localized temperature increases in the films, flexible plastic substrates can be used without degradation. Three different morphological systems and nanomaterials were studied: 1D (copper hydroxide nanowires), 2D (Graphene Oxide nanosheets), and 3D (cuprous oxide encapsulated by nickel oxide nanoparticles & also copper nitrate hydroxide nanoparticles). The nanomaterials were rapidly reduced into
conductive films via Intense Pulsed Light Processing aided through the organic decomposition of additives, providing a reducing environment. Through inclusion of different materials and morphologies, nanoscale manipulations can lead to breakthroughs in advanced materials and additive manufacturing. Cu
2O (20nm) nanoparticles encapsulated with a NiO layer were synthesized to explore protecting the Cu from oxidation and diffusion into Si based photovoltaic applications. The room temperature synthesis and IPL processes easily prevented formation of alloys at the copper-nickel interface. The encapsulation was shown to reduce Cu diffusion into Si. Copper nitrate hydroxide, Cu
2(OH)
3NO
3, was synthesized under ambient conditions with copper nitrate and potassium hydroxide reagents and processed by IPL. Films were deposited by screen-printing and then subjected to IPL Processing. Since Cu
2NO
3(OH)
3 isn’t a thermally stable material, initially transformed into CuO. However, when fructose or glucose were intentionally included as additives in the
inks, IPL Processing provided direct conversion of the Cu
2(OH)
3NO
3 into Cu. Between the two sugars, fructose was more advantageous as it led to faster reduction and lower sheet resistances, with the lowest sheet resistance being 0.224 Ω/□.
Graphene oxide was reduced with Intense Pulsed Light Processing to explore potential towards scalable
conductive films without the need for harsh/toxic reductants. The graphene oxide films on displayed a four magnitude decrease in sheet resistance from 55.1 MΩ/□. to 2280 Ω/□ after IPL. Plastic substrates required less energy to display reduction, with a four magnitude decrease in sheet resistance (62.5…

▼ Ce projet vise à développer de nouvelles encres à base de nanofils d’argent et de nanocellulose pour des applications conductrices et transparentes. Les nanocelluloses, nanoparticules issues de la cellulose, sont de deux types : les nanocristaux de cellulose (NCC) et les nanofibrilles de cellulose (NFC) et possèdent des propriétés bien spécifiques. Ce travail a consisté d’une part (i) à utiliser la forme tubulaire et rigide des NCC pour produire des nanotubes d’argents par synthèse chimique, avant leur formulation en encre et d’autre part (ii) à utiliser les propriétés d’enchevêtrement des NFC flexibles pour stabiliser des nanofils d’argent commerciaux, habituellement instables en suspension. Les divers résultats de ce projet ont permis d’aboutir à la formulation brevetée et à la commercialisation d’une encre conductrice à base d’une faible quantité d’argent et de NCC et de deux encres conductrices et transparentes à base de NFC et de nanofils d’argent. Les interactions physico-chimiques et la stabilité colloïdale de ces suspensions hybrides ont été étudiée de manière fondamentale, tout en développant des formulations adaptées à divers procédés d’impression, que ce soit à échelle laboratoire mais aussi industrielle.
This project aims at developing new conductive inks based on nanocellulose and silver nanowires for transparent and conductive applications. Nanocellulose are nanoparticles extracted from the cellulose and two kinds currently exist: the cellulose nanocrystals (CNC) and the cellulose nanofibrils (CNF). This project have evaluated on one hand the ability of using tubular rigid CNC as template for producing silver nanorods, prior their formulation into conductive inks. On the other hand, the ability of using flexible and entangled CNF to stabilize commercial silver nanowires, usually unstable in suspension, was investigated. The results of this project lead to the patented formulation and commercialization of one low silver content conductive ink based on silver and CNC and two conductive transparent ink based on CNF and silver nanowires. Physico-chemical interactions and colloidal stability of such hybrid suspension have been scientifically studied meanwhile printing process adapted formulation have been successfully designed and tested at laboratory scale but also industrial scale.

▼ This thesis describes the development and performance of novel photocatalytic inorganic polymer (geopolymer) composites for photodegradation of environmentally harmful organic materials. Nanometer-sized cubic cuprous oxide nanoparticles and spherical Cu₂O/TiO₂
nano-heterostructures were synthesized via a precipitation method and then added to a metakaolinite-based geopolymer matrix prior to curing at ambient temperature.
The morphology of the homogeneous oxide nanoparticle dispersion within the geopolymer matrix was demonstrated by SEM/EDS and HRTEM. FTIR spectroscopy confirmed the formation of a well-reacted geopolymer matrix that was unaffected by the insertion of the Cu₂O and Cu₂O/TiO₂ nanoparticles. The structures of these new composites were determined by ²⁷Al and ²⁹Si MAS NMR spectroscopy. ⁶³Cu NQR spectroscopy and XRD confirmed that the metal oxide nanoparticles are unchanged by their incorporation in the geopolymer composite and after the photodegradation reactions. The nitrogen adsorption-desorption isotherms were determined, providing information about the specific surface areas and total pore volumes of the composites. The action of the composites in the adsorption and photocatalytic destruction of the model organic compound MB was determined under dark and UV illumination conditions. Experiments in dark conditions and under UV irradiation showed that these materials efficiently remove a model organic pollutant (MB dye) from solution by a dual process of adsorption on the geopolymer matrix, and photodecomposition of the dye without destroying the geopolymer structure. The adsorption kinetics of the dye are best described by a pseudo first-order model and the adsorption process by Langmuir-Freundlich isotherms.
In a novel extension of this research, the metakaolinite-based geopolymer matrix was modified with a surfactant (cetyltrimethylammonium bromide, CTAB), exploiting the cation exchange capacity of the geopolymers structure. The
nano oxide composites were synthesised by adding different amounts of as-prepared metal oxide nanoparticles to the modified geoplymer to produce a hydrophobic photocatalyst composite with improved photocatalytic activity arising from the dispersion of the metal oxide nanoparticles in the external surfaces and interlayers of the geopolymer matrix. This method has the advantage of producing geopolymer composites with a stable pH which are more suitable for dye degradation studies.
At concentrations >20 wt%, the photo-oxide component decreases the adsorption rate by blocking the active adsorption sites of the geopolymer. Under UV radiation, the composites remove the MB by a combination of adsorption and photodegradation, without deterioration of the geopolymer structure or the photoactive metal oxide component.
In addition these studies show that the metal oxide-geopolymer
nano composites have significantly improved photocatalytic activity compared with the oxide nanoparticles alone, because of the unique properties of these inorganic polymers. These results demonstrate that…

▼ The effect of simulated environmental exposure conditions (high heat, freezing
temperature, rain, and vacuum pressure) on the performance of a silver-based
conductive
flexo ink printed on a polyamide (nylon 6,6) substrate was examined. Conductivity,
density, color, adhesion, abrasion resistance and creasing were evaluated.
The tested environmental variables did not have an effect on the performance
quality of silver
conductive flexographic ink when printed on a polyamide substrate for
the 85 – 100% solid ink density levels. Rain and temperature had the greatest impact on
print performance in the 70–80% tint range. Exposure to these elements affected
adhesion properties of the ink to the substrate, which lead to a negative effect on the
conductivity and abrasion performance.
This study indicated an antenna printed at common ink density levels using a
silver-based flexographic printing ink on a polymeric film is a possible solution for the
implementation of printed RFID components. This is a manufacturing option that can
bring the packaging industry from a "slap and stick" RFID labeling method to an actual
inline production method that can be applicable to both primary and secondary package
tagging needs. Lastly, the study utilizes common ink testing procedures that will be
useful in the development of standards for the production of printed RFID components in
packaging applications.

▼ For the continued advancement of the field of printed electronic (PE), there is a need for a better understanding of the interactions between functional
inks and substrates, which is required to optimize printability, mechanical, and functional properties for the creation of more robust and efficient printed devices. This body of work aims to advance the knowledge of the material properties of poly-di-methyl-siloxane, PDMS, films, their interactions with flexo
inks, and their flexographic printability. As the printing of metals (i.e., Ag & Au) is a known area of interest pertaining to PE, this work focused on the characterization and optimization of the properties known to promote the adhesion between materials, and their effects on the functional performance of printed
conductive ink films. PDMS is an especially important substrate for use in the creation of biocompatible sensors and devices, which is an area predicted to experience much growth in the coming years. But, PDMS has known complications pertaining to its printing and adhesion of materials to its surface. To accomplish this goal, four studies were completed: 1- The Characterization of Surface Treated Silica-Filled and Non-Filled Polydimethylsiloxane Films, 2- Use of Atmospheric-Plasma Treatment to alter the Surface Energy of PDMS Films, and 3- Feasibility for the Development of a Repulpable Silicone Release Paper. From these studies, a need for a high throughput processing and production method for rol-to-roll production and printing of thin (<100 micron) PDMS films was realized and a fourth work performed 4- A Novel Method for the High Throughput Processing and Production of Thin (<100 micron) PDMS Films in which novel method for the roll-to-roll printing of PDMS films was created. The results of these studies provide information on the influences of surface treatments and material interactions on the printability of PDMS films.

▼ In this study, polyol method was used to synthesize
nano-silver. The first part is the analysis of silver nanoparticles (AgNPs) synthesized by polyol method. The ethylene glycol (EG) was reducing agent and solvent. Polyvinylpyrrolidone (PVP) and silver nitrate (AgNO3) were dispersant and silver additive, respectively. Then, the AgNPs were extracted and electrospun on printed circuit board by electrospinning process and then collected by Ostwald ripening process. Next, the sheet resistance of AgNPs was measured by four-point probe. The ingredient of AgNPs was determined by energy-dispersive X-ray spectroscopy and the morphology of AgNPs was observed by scanning electron microscope. The second part was analysis of optimal silver nanowire (AgNWs). The Taguchi and uniform design were adopted to investigate the influence of synthesis parameters on aspect ratio of AgNWs and obtain optimal AgNWs used to fabricate film. Moreover, the electrical and optical properties were measured. This study shows that the diameter of AgNPs synthesized by low molecular weight PVP was small and uniform. For the Ostwald ripening process, the aggregated effect of AgNPs was more obvious with higher concentration and longer time of vibration of AgNPs. For the Taguchi analysis of AgNWs, the optimal parameter was 0.21g PVP, 0.065g silver chlorine (AgCl), 0.22g AgNO3 and 72.9 ± 6.6 aspect ratio. For the uniform design, the rank of influence of parameters on aspect ratio of AgNWs was PVP > AgNO3 > AgCl. Then, the optimal AgNWs were used to fabricate AgNWs transparent
conductive film. For the film, the transmittance was 52% when the thickness was 705.9à and the sheet resistance was 53.128 MΩ/sq. The transmittance was 18% when the thickness was 2918.0à and the sheet resistance was 20.098 kΩ/sq.

▼ Clean and affordable energy, especially solar energy, is becoming more and more important as our annual total energy consumption keeps rising. However, to make solar energy more affordable and accessible, the cost for fabrication, transportation and assembly of all components need to be reduced. As a crucial component for solar cells, transparent
conductive electrode (TCE) can determine the cost and performance. A light weight, easy-to-fabricate and cost-effective new generation TCE is thus needed. While indium-doped tin oxide (ITO) has been the most widely used material for commercial applications as TCEs, its cost has gone up due to the limited global supply of indium. This is not only due to the scarcity of the element itself, but also the massive production of various opto-electronic devices such as TVs, smartphones and tablets. In order to reduce the cost for fabricating large area solar cells, substitute materials for ITO should be developed. These materials should have similar optical transmittance in the visible wavelength range, as well as similar electrical conductivity (sheet resistance) to ITO. This work starts with synthesizing ITO-replacing
nano-materials, such as copper nanowires (CuNWs), derivative zinc oxide (ZnO) thin films, reduced graphene oxide (rGO) and so on. Further, we applied various deposition techniques, including spin-coating, spray-coating, Mayer-rod coating, filtration and transferring, to coat transparent substrates with these materials in order to fabricate TCEs. We characterize these materials and analyze their electrical/optical properties as TCEs. Additionally, these fabricated single-material-based TCEs were tested in various lab conditions, and their shortcomings (instability, rigidity, etc.) were highlighted. In order to address these issues, we hybridized the different materials to combine their strengths and compared the properties to single-material based TCEs. The multiple hybridized TCEs have comparable optical/electrical metrics to ITO. The doped-ZnO TCEs exhibit high optical transmittance over 90% in the visible range and low sheet resistance under 200Ω/sq. For CuNW-based composite electrodes, ~ 85% optical transmittance and ~ 25Ω/sq were observed. Meanwhile, the hybridization of materials adds additional features such as flexibility or resistance to corrosion. Finally, as a proof of concept, the CuNW-based composite TCEs were tested in dye-sensitized solar cells (DSSCs), showing similar performance to ITO based samples.

▼ This thesis covers the interaction of a femtosecond pulsed laser (about 150 fs
at FWHM) with spherical gold
nano-particles (100 nm in diameter) in the abla-
tion regime. The study is separated into an experimental part and a simulation
part.
For the experimental part, gold
nano-particles are isolated by the drop cast-
ing technique on a substrate. Scanning electron microscope data is used as
a mapping system for our diffraction limited optical ablation setup. The self-
scattering of the
nano-particles as a function of fluence is investigated. We found
the ablation threshold to be about 0.03 J/cm
2 and reached a maximum fluence
of about 0.2 J/cm
2 . The self-scattering results from ablated
nano-particles are
inconclusive due to a high background contribution from the substrate.
The simulation part covers the light scattering properties of gold
nano-
particles sized around the Rayleigh limit. Due to high electron temperatures
reached (2/3 of the Fermi temperature for gold) in femtosecond laser-gold inter-
action, we incorporate ab initio data by Lin and Zhigilei on the electron heat
capacity into our model. We also include experimental data by Fourment et al.
on the number of free conduction electrons per atom. Results show a decrease
in reflectivity during irradiation at a fluence of 0.8 J/cm
2 . The model allows to
go up to a fluence of 10 J/cm
2 , where we observe a decrease in reflectivity of
about 10 %.

▼ The central theme of this Ph.D. dissertation is to develop novel multifunctional
polymer coatings for understanding partition of proteins and nanoparticles on polymers
grafted to flat surfaces (so-called brushes). Systematic investigation of the adsorption
phenomena is accomplished by utilizing surface-anchored assemblies comprising grafted
polymers with variation in physical properties (i.e., length or/and grafting density) and
chemical functionality. The chemical composition of the brush is tailored by either
“chemical coloring†of a parent homopolymer brush with selective chemical moieties or by
sequential growth of two chemically dissimilar polymer blocks. We present preparation of
two types of tailor-made, surface-grafted copolymers: 1) those composed of hydrophilic and
hydrophobic blocks (so-called amphiphilic polymer brushes), and 2) those comprising of
anionic and cationic polymer segments (so-called polyampholyte brushes). We describe the
organization of functionality in the grafted polymer brushes and the partitioning of proteins
and nanoparticles using a battery of complementary analytical probes. Specifically, we
address how varying the molecular weight, grafting density, and chemical composition of the
brush affects adsorbtion and desorbtion of model proteins and gold nanoparticles. Our
observations indicate densely-populated responsive amphiphilic polymers are very efficient
in suppressing protein adsorption. In addition, we have established that the length of poly(ethylene glycol) spacers attached to a parent homopolymer brush is a key factor
governing uptake of gold nanoparticles. Both grafting density and molecular weight of the
coating are important in controlling the kinetics and thermodynamics of protein adsorption
on surfaces. Our findings and methodologies can lead to the development of next generation
environmentally friendly antifouling surfaces and will find application in medical devices,
antifouling coatings and anti reflection finishes.

▼ In addition to low cost and high volume, continuous production of devices such as
transistors and RFID tags, printable electronics show promise in the fabrication of a
multiplicity of sensors, displays, photovoltaic arrays, smart cards, etc. Due to flexibility
and insensitivity to substrates, the use of organics in printed electronics has opened up a
number of new opportunities in novel applications.
In the present work, the process capability of flexography and offset lithography for
patterning
conductive materials was determined using small scale equipment (rotary
letterpress and duplicator respectively). Process parameters including: type of substrate,
line widths, line gaps, print thickness, directional effects, etc. were investigated. It was
thus shown that the high volume printing processes of offset lithography and flexography
can be used to obtain functional printed
conductive patterns.
In order to have greater control over ink composition and physical characteristics than
was afforded by commercially available silver metal filled
conductive inks, polyaniline
(PANI) was synthesized by interfacial polymerization. Printable flexographic
inks were
formulated therefrom and a PANI ink was used in the flexographic printing of a working
gas sensor. The conductivity of these
inks was lower than that of silver filled metallic
inks. This mitigated their utility in their utility in the printing of functional RFID
antennae.
Poly (thiophene-2, 5-diyl) (PT) and its derivatives are perhaps the most extensively
studied class of conducting polymers and find applications in a variety of organic
electronic devices. In the present work, an unprecedented approached to the synthesis and
formulation of solution processible polythiophene (PT) compositions was explored.
Conducting composites of polythiophene were synthesized by oxidative coupling of
bithiophene, catalyzed by Fe3+ bound to the amphiphilic segment of functional block
copolymers. Thus, amphiphilic block copolymers such as polystyrene-b-polyethylene
oxide (PS-PEO) and polystyrene-b-polyacrylic acid (PS-PAA) complexed with Fe3+ were
utilized as templates in the formation of soluble/redispersible prototype
inks. The
distribution of the
conductive phase is, in principle, determined by the morphology of the
block copolymer. The composites were characterized by DSC, UV-vis and IR
spectroscopy. PT formed in the presence of these amphiphilic block copolymers was
oxidised using suitable doping agents. The compositions however failed to exhibit
significant conductivity.
A number of challenges must be overcome in order to realize the potential economic
benefits of using organic polymers in large scale electronic printing applications. The
conductivity of
inks based on organic conducting polymers can be increased by
increasing the overall volume fraction of the
conductive entity. The adhesion of the PANI
compositions on various substrates could be improved by addition of a binding agent at a
level that does not adversely affect the conductivity of the
inks. Opportunities afforded…

▼ Abstract
In gravure offset printing, ink is transferred with the help of an offset material from a patterned gravure plate to a substrate. This thesis is concerned with the study and further development of this printing process for electronics; on alumina, glass and polymers.
The work has been divided into five parts. In the first section, the printing process is described. The second section describes the composition of the inks for gravure offset printing and the resulting ink properties. It also presents the ink transfer mechanism; the model that explains how the ink is transferred between an offset material and a substrate. The third chapter details the printing process explained by a solvent absorption mechanism. The forth chapter describes the firing/curing of printed samples and their properties. The last chapter describes applications of the method.
The inks used to produce conductors on ceramics (ceramic inks) and conductors on polymers (polymer inks) contain silver particles, and were under development for gravure offset printing. The major achieved properties were the high ink pickup to the offset blanket and high transfer percentage to the substrate. 100% ink transfer from blanket to substrate for ceramic inks and almost 100% ink transfer for polymer inks was obtained. The printing of ceramic inks was able to produce 8 μm of relatively thick, 300 μm wide lines with < 10 mΩ/sq. resistance. The minimum line width for conducting lines was 35 μm, with one printing. Multi printing was applied producing as many as 10 times wet-on-wet multiprinted lines with 100 % ink transfer from blanket to substrate resulting in a square resistance of 1mΩ/sq. Polymer inks were able produce a square resistance of 20 mΩ/sq. for 300 μm wide lines after curing at 140 °C for about 15 min, and the minimum width was down to 70 μm.
In the optimised manufacturing process, the delay time on the blanket was reduced to 3 s. In addition to ultra-fine-line manufacturing of conductors, the method enables the manufacture of special structures e.g. laser-solder contact pads with 28/28 μm lines/spaces resolution. With industrial printing equipment it is possible to produce 100 m2/h with the demonstrated printing properties.

Printing Conductive Inks on Nonwovens: Challenges and Opportunities.

▼ Flexible printed circuit boards continue to be a high-growth technology in the area of electrical interconnectivity. Over traditional rigid printed circuit boards (PCB's), wire and wire harnesses, flexible circuit boards provide considerable weight, space, and cost savings This study investigates using
conductive inks for printing circuits onto flexible nonwoven substrates as a low-cost alternative to traditional PCB manufacturing, because the emerging generation of nonwovens can offer wearability, printability, lightweight, durability and washability.
In this study, instead of incorporating
conductive paths by weaving or knitting
conductive yarns into the structure of the fabrics,
conductive inks are used to print directly onto nonwovens by using polymer thick film technology. There are challenges in printing on fabrics such as achieving printing resolution and durability. Spatial geometry of structure is a critical property for print resolution. The traditional woven fabrics exhibit poor digital printability because the ink disperses mostly through the inter-yarn interstices. The spatial resolution is primarily a function of yarn diameter and thread spacing (e.g., end and picks per inch in woven fabrics). Consequently, in woven fabrics, fine spatial resolution is only possible in high density, light weight, densely structures. Even in the case of such light weight structures, the surface texture can be quite rough for printing purposes. Additionally, light weight fabrics can be limited with respect to properties they offer. Other structural factors such as yarn twist and fiber properties are also factors that may affect the absorbency and the wicking of the ink into the structure and therefore, can limit the utility of the printed circuit lines. In contrast, the new generation of durable micro-fiber nonwoven fabrics offers the opportunity to "engineer" the structure surface properties, the network geometry and the capillary structure to optimize their use for printing. Nonwovens offer the ability to easily manipulate pore size and geometry and create an abundance of small capillaries. Today, it is possible to produce heavy fabrics with fine fibers and different surface textures using nonwovens much more cost effectively than their woven or knitted counterparts. As in other fabrics, the ink substrate interaction determines the printability on nonwoven fabrics. In the case of nonwovens, the main parameters affecting the printability are surface energy of the fibers, fabric structure (fiber orientation distribution), fiber size (controlling surface roughness and pore size) and ink viscosity. Fundamentally, because we are dealing with a porous network as opposed to a non-porous film, the interaction of ink droplet with the structure with respect to its movement in-plane as well as through-the-plane determines the quality of the printing that is achieved. Thus, to control the distribution of the ink on and into the fabric, we have to have control over the structure.
The first chapter outlines and examines…

▼ Printed electronics (PE) are being developed as an alternative to traditional electronics, due to the more efficient use of materials and lower cost of production. The overall goal of this study was to understand how metallic pigments in
conductive inks in PE are partitioned during landfill disposal and paper recycling conditions. The purpose is to assess the potential environmental impacts of PE landfilling in terms of metal leaching and to help develop new strategies for sequestering metallic ink components while paper-based PE are subjected to conventional paper recycling methods. The objective of this research is to study the fate of PE metallic pigments by analyzing how metals partition across different streams in the recycled papermaking system, the potential leaching characteristics of the
inks, and the ink film characteristics on paper that will help to show whether or not the metallic pigments can be removed from the paper fibers. Three studies were conducted to address each of these specific objectives In the first study, three
conductive inks used to create PE - nickel, silver flake and nanoparticle
inks were printed on label paper substrates simulating PE materials, which were then pulped and screened in benchscale experiments. Accepts, rejects, and wastewater streams were collected and analyzed using Atomic Absorption Spectrometry (AAS) to measure the metal concentrations in each stream and create a material balance around the pulping and screening process. Results showed that for the nickel and silver flake
inks the metallic pigments partitioned mostly into the “accepts” stream, while for silver nanoparticle
inks, the metallic pigments were partitioned mostly to the wastewater stream. The second study involved landfill simulation experiments to evaluate the potential leaching of metal pigments from polymer and paper based PE while subjected to landfilling conditions using EPA methods 1311 (Toxicology Characteristic Leaching Procedure) and Hazardous Waste Test Method - SW 846. Results show that the nickel ink used could potentially form hazardous leachate if landfilled, because it crossed 5 parts per million in the leachate. The silver
inks did not cross 5 parts per million threshold named in the Toxicology Characteristic Leaching Procedure (TCLP) test and do not pose a leaching potential in a landfill at the weight fractions tested. The third study involved a qualitative assessment of nickel and silver
conductive ink penetration and adsorption/absorption characteristics in paper substrates using scanning electron microscopy (SEM). From these microscopic observations, we can substantiate the findings from the re-pulping and screening test when talking about removing and recovering these pigments from the paper fibers during recycling. Results showed that nickel and silver flake
inks do not penetrate the fiber pores and are mostly concentrated in the paper substrate surface, but appear to have become attached or bonded to the fiber surface in some regions. The silver nanoparticle pigments have migrated…

▼ Ces travaux examinent le potentiel d’un papier à fort lissé pour la production de masse de tags RFID-HF imprimés. Les caractérisations menées sur le papier Powercoat HD mettent en évidence une haute tolérance à la température et une faible rugosité. De fait, il se présente ainsi comme une sérieuse alternative à l’utilisation des films polymères (PET, PEN, PI, etc.), permettant de développer pleinement les performances électriques d’encres conductrices métalliques.Deux procédés d’impression industriels ont été considérés, la flexographie et la sérigraphie ayant tout deux fait leurs preuves depuis plusieurs décennies pour l’impression graphique à hautes cadences. Le potentiel de leur utilisation pour l’impression à grande échelle de dispositifs électroniques à bas-coût est discuté dans ces travaux. De plus, les performances électriques d’encres commerciales à base d’argent sont étudiées en fonction de la taille des particules qui les composent. En effet, l’utilisation de particules métalliques à l’échelle nanométrique pourra faciliter l’activation des mécanismes de diffusion atomique, améliorant ainsi le contact physique entre les particules et favorisant la conduction électrique. En parallèle, les encres à microparticules sont moins coûteuses et leurs conditions d’utilisation moins contraignantes. Toutefois, la coalescence des particules métalliques après l’impression ne pourra être initiée sans un traitement thermique de recuit.Le recuit est usuellement réalisé dans une étuve ou un tunnel à air chaud, la température doit alors rester inférieure à la tolérance du substrat. Cela permet d’atteindre des performances électriques qui restent limitées pour des durées de procédé de l’ordre de plusieurs minutes. Afin de tenir compte des contraintes industrielles d’une production à grande échelle et de permettre d’obtenir les meilleures performances électriques en un temps réduit, l’un des principaux axes de recherche exploré consiste au déploiement des technologies émergentes de recuit photonique proche infrarouge (NIR) et lumière intense pulsée (IPL). Ces dernières sont basées sur l’absorption de l’énergie lumineuse par le film d’encre provoquant ainsi sont échauffement rapide. L’important différentiel d’absorption entre les encres et le substrat contribue, en outre, à une sélectivité de ces procédés permettant de limiter la dégradation du support tout en atteignant au niveau de l’encre, des températures pouvant être supérieures à 300°C. Pour chaque procédé de recuit, l’influence des différents paramètres sur les performances électriques finales a pu être étudiée par la mise en place d’un suivi in-situ de la résistance, permettant un échantillonnage allant jusqu’à 250 kHz.Finalement, des boucles RFID-HF ont été imprimées, recuites dans les conditions précédemment optimisées puis caractérisées. Une estimation des coûts de production a été menée afin de distinguer les contributions liées à l’encre, au support et à la puce électronique en silicium. Les résultats obtenus mettent en évidence le potentiel du papier Powercoat HD,…

▼ Impressive revolution of optical imaging and microscopy architectures has been expanding our horizon and increasing the opportunities in medical diagnostics. Although we experience significant advancements such as better resolution, speed and throughput, advanced imaging platforms are still complex, bulky and expensive, such that their function beyond well-established clinical environment is quite limited. Therefore, innovative imaging techniques are necessary to combat global health problems in resource-scarce settings where health care infrastructure is extremely limited or does not even exist. In such poor settings, imaging devices should be compact, robust, cost-effective and easy to use, without a trade-off in their performance.Centered on this vision, here I demonstrate a new lensfree on-chip microscopy and nano-particle imaging platform based on partially-coherent digital in-line holography, providing a highly-sensitive and high-throughput approach for rapid medical diagnostics and screening, especially for field settings and resource-limited environments. This computational microscopy and nano-particle imaging platform achieves subcellular spatial resolution and also directly images, for the first time in on-chip microscopy, single sub-100 nm particles using self-assembled aspheric liquid nano-lenses around individual nano-particles across a large field-of-view of >20 mm2, i.e., more than two orders-of-magnitude larger than existing nano-imaging techniques.This platform does not utilize any lenses, lasers or other bulky optical/mechanical components which greatly simplifies its architecture making it portable, light-weight, and cost-effective. It has been successfully implemented on a compact stand-alone unit which weighs only ~46 grams with dimensions smaller than 4.2 x 4.2 x 5.8 cm as well as on a commercially-available cell-phone that is modified with a light-weight (~ 38 grams) hardware attachment.Using stable and biocompatible wetting films to self-assemble aspheric liquid nano-lenses around individual nano-particles, I also introduce a wide-field on-chip microscopy modality that is capable of directly imaging single nano-particles and viruses (i.e., adenoviruses and influenza A (H1N1) viral particles) within a field-portable design.Creating new opportunities for rapid medical diagnostics in point-of-care and field conditions, this lensfree microscopy and nano-particle imaging toolset may bring improved healthcare delivery especially to resource-poor regions of the world and may significantly benefit our fight against various global health challenges including HIV, malaria, waterborne diseases and viral infections.

▼ A confocal micro-particle image velocimetry (C-μPIV) technique along with associated post-processing algorithms is detailed for obtaining three dimensional distributions of nano-particle velocity and concentrations at select locations of the 2.5D (pseudo 3D) Poly(methyl methacrylate) (PMMA) and ceramic micro-model. The designed and fabricated 2.5D micro-model incorporates microchannel networks with 3D wall structures with one at observation wall which resembles fourteen morphological and flow parameters to those of fully 3D actual reservoir rock (Boise Sandstone) at resolutions of 5 and 10 μm in depth and 5 and 25 μm on plane. In addition, an in-situ, non-destructive method for measuring the geometry of low and high resolution PMMA and ceramic micro-models, including its depth, is described and demonstrated. The flow experiments use 860 nm and 300 nm fluorescence-labeled polystyrene particles, and the data is acquired using confocal laser scanning microscopy. Regular fluorescence microscopy is used for the in-situ geometry measurement along with the use of Rhodamine dye and a depth-to-fluorescence-intensity calibration, which is linear. Monochromatic excitation at a wavelength of 544 nm (green) produced by a HeNe continuous wave laser was used to excite the fluorescence-labeled nanoparticles emitting at 612 nm (red). Confocal images were captured by a highly sensitive fluorescence detector photomultiplier tube. Results of detailed three dimensional velocity, particle concentration distributions, and particle deposition rates from experiments conducted at flow rates of 0.5 nL/min, 1 nL/min, 10 nL/min and 100 nL/min are presented and discussed. The three dimensional micro-model geometry reconstructed from fluorescence data is used as the computational domain to conduct numerical simulations of the flow in the as-tested micro-model for comparisons to experimental results using dimensionless Navier-Stokes model. The flow simulation results are also used to qualitatively compare with velocity distributions of the flowing particles at selected locations. The comparison is qualitative because the particle sizes used in these experiments may not accurately follow the flow itself given the geometry of the micro-models. These larger particles were used for proof of concept purposes, and the techniques and algorithms used permit future use of particles as small as 50 nm.

▼ Approaches to prepare spatially selective surfaces were developed in this dissertation for constructing nanopatterns of organic thin film materials. Nanoscale surface patterns were prepared using immersion particle lithography and scanning probe lithography combined with organothiol chemistry. Organic thin films and nanomaterials can be patterned with tunable periodicities and designed shapes by selecting the diameter of mesospheres used as surface masks or scanning probe lithography, respectively. The surface platforms of well-defined nanopatterns are ideal for high resolution investigations using scanning probe microscopy (SPM). Local measurements of surface properties and conductive properties combined with nanolithography were accomplished at the molecular level. Sample characterizations were accomplished with selected modes of SPM. Scanning probe studies can be used to probe the morphological and physical properties of samples, when spatially confined nanomaterials are prepared. Atomic force microscopy (AFM) can be used to analyze many types of samples in ambient and liquid environments. Arrays of nanostructures formed with newly designed molecules and porphyrins were fabricated using the spatial selectivity of chemical patterns prepared with nanolithography. The designed nanopatterns were evaluated for morphological details and physical properties. A newly designed bidentate organosulfur compound, i.e. 16-[3,5-bis(mercaptomethyl)phenoxy] hexadecanoic acid (BMPHA), was selected for study. The solution phase self-assembly onto Au(111) was investigated with scanning probe-based nanolithography and particle lithography. The two thiol groups of BMPHA were specially designed as surface linkers for improved stability. The orientation of BMPHA on Au(111) was investigated by referencing the heights of n-alkanethiols as an in situ molecular ruler. Protocols for patterning porphyrin nanostructures i.e. nanodots and nanorods on Au(111) were developed based on protocols with immersion particle lithography. Porphyrins with and without a central metal ion, 5,10,15,20-tetraphenyl-21H,23H-porphine (TPP) and 5,10,15,20-tetraphenyl-21H,23H-porphine cobalt(II) (TPC) were patterned using immersion particle lithography. Individual nanorods and nanodots of porphyrins were spatially isolated into well-defined, nanoscale arrangements directed by a template film of a nanopatterned thiol monolayer. The conductivity of the nanostructures of the porphyrins was evaluated using conductive probe-atomic force microscopy (CP-AFM). The studies evaluate the applicability of nanolithography for preparing surface platforms for the measurements of morphological and physical properties at the nanoscale.

▼ Le potentiel des procédés d’impression dans les applications électroniques sur des supports en céramique a été démontré dans ce travail. Plusieurs techniques d’impression ont été étudiées : sérigraphie, flexographie, héliogravure et jet d’encre. Les propriétés de surface de plusieurs types de céramique ont été caractérisées avant et après frittage : taille des pores, rugosité et énergie de surface. Ces analyses ont permis de sélectionner les matières premières des encres les mieux adaptées à ces supports, ainsi qu’aux procédés d’impression considérés. Des formulations aqueuses à base de particules d’argent ont été privilégiées. Les propriétés de ces encres, rhéologie et tension de surface, ont été analysées et leurs effets sur la qualité des lignes imprimées (largeur, épaisseur et rugosité) ont été évalués. Après impression, les motifs ont été frittés. Des résistivités proches de celle de l’argent ont été obtenues (2 à 12x10-8 Ohm.m). L’originalité de ce travail réside notamment dans l’utilisation d’encres sérigraphiques à base d’eau et l’impression d’encres flexographiques sur des supports en céramique. Cette étude ouvre donc des perspectives pour l’industrialisation et la production de masse de composants électroniques sur supports céramiques souples.
This work demonstrates the printing processes potential for manufacturing ceramic based electronic devices. Several printing techniques were studied: screen printing, flexography, rotogravure and inkjet. Ceramic tapes surface properties were characterised: surface pore size, roughness and surface energy. These analyses allowed the selection of the inks raw materials adapted to the substrates and the printing processes. Water-based silver inks were formulated. Inks properties, rheology and surface tension, were analysed and their effect on line properties was investigated. Printed substrates were afterwards sintered. Resistivity values close to that of bulk silver were reached (2 to 12x10-8 Ohm.m). These work novelties are mainly the formulation of water-based environmentally friendly screen printing pastes and the flexography printing of silver inks onto ceramic substrates. This study offers new perspectives for the industrialisation and the mass production of electronic components on flexible ceramic substrates.

▼ In the past 30 years zero-valent iron (ZVI) has become an increasingly popular reducing agent technology for remediating environmental contaminants prone to chemical degradation. Azo dyes and chlorinated organic compounds (COCs) are two classes of such contaminants, both of which include toxic compounds with known carcinogenic potential. ZVI has been successfully applied to the surfaces of permeable reactive barriers, as well as grown into nanoscale particles (nZVI) and applied in-situ to chemically reduce these contaminants into more environmentally benign compounds. However, the reactivity of ZVI and nZVI in these technologies is limited by their finite supply of electrons for facilitating chemical reduction, and the tendency of nZVI particles to homo-aggregate in solution and form colloids with reduced surface area to volume ratio, and thus reduced reactivity. The goal of this project was to combine reactive nanoparticle and membrane technologies to create an electro-catalytic permeable reactive barrier that overcomes the weaknesses of nZVI for the enhanced electrochemical filtration of azo dyes in solution. Specifically, nZVI was successfully grown and stabilized in a network of functionalized carbon nanotubes (CNTs) and deposited into an electrically conductive thin film on the surface of a polymeric microfiltration support membrane. Under a cathodic applied voltage, this thin film facilitated the direct reduction of the methyl orange (MO) azo dye in solution, and regenerated nZVI reactivity for enhanced electro-catalytic operation. The electro-catalytic performance of these nZVI-CNT membrane surface composites to remove MO was validated, modelled, and optimized in a batch system, as well as tested in a dead-end continuous flow cell system. In the batch experiments, systems with nZVI and a -2 V applied potential demonstrated synergistic enhancement of MO removal, which indicated the regeneration of nZVI reactivity and allowed for the complete removal of 0.25 mM MO batches within 2-3 hours. Partial least squares regression (PLSR) modelling was used to determine the impact of each experimental parameter in the batch system and provided the means for an optimization leading to maximized MO removal. Finally, tests in a continuous system yielded rates of MO removal 1.6 times greater than those of the batch system in a single pass, and demonstrated ~87% molar removal of MO at fluxes of approximately 422 lmh. The work herein lays the foundation for a promising technology that, if further developed, could be applied to remediate azo dyes and COCs in textile industry effluents and groundwater sites respectively.

▼ A manufacturing technology is proposed to manufacture polymeric membrane scaffolds for culturing of cells, tissues, and organoids with integrated sensor capabilities and fluidic functionalities. A multilayer substrate is imprinted with a soft mold to manufacture polymeric membrane scaffolds for culturing of cells, tissues, and organoids with integrated sensor capabilities and fluidic functionalities. Aside from exploiting the well characterized, simple and low cost techniques that can be employed in polymer manufacturing, the use of solely polymeric materials increases the opportunities for functional integration, while at the same time allowing for the translation of complex cleanroom fabrication processes into mold-based replication techniques. With this developed manufacturing technology, it is demonstrated that it is possible to manufacture membrane scaffolds with integrated porous electrode up to 1mm by 1mm in effective surface area, with a thickness of 10 µm, with control over the pore diameter (as small as 400 nm), the porosity, and the location of the pores. The morphological characterization is done by scanning electron microscopy. The integrated porous electrode’ performance is characterized electrically by a 4-point probe and electrochemically by cyclic voltammetry and electrochemical impedance spectroscopy. Showing the possibility to use the conductive layer to give cells electrical stimuli and for the use as a biosensor.

▼ Après l'agriculture, l'industrie textile a engendré un important problème de pollution de l'eau car la plupart des produits chimiques provenant de ces industries sont hautement toxiques et affectent directement ou indirectement la santé humaine. La pollution électromagnétique (EM) est un autre problème important qui détériore les performances et la durée de vie des objets électroniques et nuit également à la santé humaine. Dans ce contexte, la nature fibreuse inhérente des nanomatériaux cellulosiques et leurs propriétés mécaniques remarquables, associées à une biocompatibilité et à une ressource durable, offrent un potentiel énorme en tant que composant dans les membranes de filtration de l'eau et les atténuateurs de micro-ondes verts. L'objectif principal de cette thèse est de fabriquer des objets fonctionnels à base de nanofibres de cellulose pour la filtration de l'eau et la suppression des micro-ondes. La méthode présentée dans ce manuscrit décrit un nouveau matériau absorbant à partir de nanofibres de cellulose par l'intermédiaire d'une méthode non solvatée utilisant l'acide de Meldrum comme agent d'estérification pour l'absorption de colorants toxiques. Cette innovation offre une nouvelle plate-forme pour le traitement de surface des nanofibres de cellulose utilisant une technologie verte sans solvant. Classiquement, les métaux ont été utilisés pour protéger les ondes électromagnétiques, mais sont fortement indésirables en raison de leurs inconvénients tels que des poids plus élevés, une nature corrosive et une difficulté de traitement en formes complexes. Les nano- papiers, à base de cellulose conductrice, peuvent offrir une solution verte à ce problème. La cellulose rendue conductrice présente une efficacité de blindage totale de plus de 20 B. Il s’agit d’une plate-forme efficace pour développer des atténuateurs verts respectueux de l'environnement.
After agriculture, the textile dyeing and finishing industry has generated a large water pollution problem as most of the chemicals coming from these industries are highly toxic and directly or indirectly affect human health. Another important issue is the Electro Magnetic (EM) pollution which deteriorates the performance and life of electronic gadgets and also adversely affects the human health. In this context, cellulose nanomaterial’s inherent fibrous nature and remarkable mechanical properties combined with low cost, biocompatibility and sustainable source, suggest huge potential as a component in water filtration membranes and green microwave attenuators in future. The main objective of this thesis is to fabricate cellulose nanofibers based functional constructs for clean water and microwave suppression. The presented unique method to produce novel absorbent material from cellulose nanofibers via non-solvent assisted method using Meldrum’s acid as an esterification agent for absorption of toxic dyes from water has not been addressed till date. This finding offers a new platform for the surface treatment of cellulose nanofibers using solvent free green…
