▼ Highly conductive and durable proton exchange membranes (PEMs) are critical to realizing alternative energy applications including fuel cells, batteries, and photochemical water splitting. A major challenge is to fabricate materials with high ionic conductivity at high operating temperature that can maintain mechanical stability. This thesis investigates (i) the use of liquid crystalline (LC) order to improve anhydrous proton transport, and (ii) the use of electrospinning to form mechanically stable membranes with high ion content. Two novel smectic liquid crystalline (LC) mesogens (Imi-COOH and Imi-DAH) were designed and synthesized with a diacylhydrazine core and a terminal proton-conducting imidazole group. In principle smectic LC ordering may offer proton-conductive pathways between smectic layers while retaining a high level of liquid-like mobility. Imi-COOH forms a smectic LC mesophase and exhibits mesoscopic order up to 230 °C, whereas Imi-DAH exhibits a less ordered nematic phase. Impedance spectroscopy studies indicate that LC ordering combined with acid-base exchange results in significantly higher proton conductivity in Imi-COOH’s LC state (δ ~10-5 S/cm) compared to Imi-DAH (δ ~10-7 S/cm). However, for Imi-DAH and DAH, the imidazole groups are relatively dilute, and LC ordering alone within microscopic polydomains does not result in significantly higher conductivity. The activation energy for proton transport is shown to be higher in the LC state compared to the isotropic liquid. Thermal activation of targeted LCs above their clearing temperature was comparable to that of liquid imidazole (~0.2-0.4 eV) and this energy scale agrees with Grothuss-like proton transport. The second part of this thesis investigates a novel approach to improve mechanical properties of PEMs through electrospinning. A series of quaternary ammonium polysulfone (QAPS) solutions with ion contents, ranging from 0.5-1.7 mmol/g, were electrospun and solvent-cast. With increasing solution concentrations, the electrospun morphology evolved from stretched spheres to uniform bead-free fibers. The as-spun QAPS mats were treated to increase membrane density and to promote 3D fibrous interconnection. Considering their high ion exchange capacities (ICEs), the electrospun membranes exhibited favorable mechanical strength compared to solution-cast films. Future composite membranes, derived from those reported here, may offer low cost, high IEC, and mechanical durability.

▼ Electrospinning has been the focus of countless studies for the past decades for applications, including but not limited to, filtration, tissue engineering, and catalysis. Electrospinning is a one-step process for producing nano- and/or micro-fibrous materials with diameters ranging typically from 50 to 5000 nm. The simulation algorithm presented here is based on a novel mass-spring-damper (MSD) approach devised to incorporate the mechanical properties of the fibers in predicting the formation and morphology of the electrospun fibers as they travel from the needle toward the collector, and as they deposit on the substrate. This work is the first to develop a physics-based (in contrast to the previously-developed geometry-based) computational model to generate 3-D virtual geometries that realistically resemble the microstructure of an electrospun fibrous material with embedded particles, and to report on the filtration performance of the resulting composite media. In addition, this work presents a detailed analysis on the effects of electrospinning conditions on the microstructural properties (i.e. fiber diameter, thickness, and porosity) of polystyrene and polycaprolactone fibrous materials. For instance, it was observed that porosity of a PS electrospun material increases with increasing the needle-to-collector distance, or reducing the concentration of PS solution. The computational tool developed in this work allows one to study the effects of electrospinning parameters such as voltage, needle-to-collector distance (NCD), or polymer concentration, on thickness and porosity of the resulting fibrous materials. Using our MSD formulations, a new approach is also developed to model formation and growth of dust-cakes comprised of non-overlapping non-spherical particles, for the first time. This new simulation approach can be used to study the morphology of a dust-cake and how it impacts, for instance, the filtration efficiency of a dust-loaded filter, among many other applications.

▼ The advantages of conducting materials in the non-woven nanofiber-mat form prepared by the electrospinning technique are proposed for sensing nanocomposite applications. Due to the sub-micron size of electrospun conducting fibers, a large specific surface area is generated, while the fiber web contains high fiber aspect ratio and high interconnecting network compared to the same materials in film and short fiber forms. Consequently electrospun lithium perchlorate doped polyethylene oxide (LiClO4-doped PEO) fibers and electrospun carbon black filled LiClO4-doped PEO composite fibers were prepared to be used as humidity sensors. The measurements of humidity dependent resistance of these conducting fibers were carried out for different humidity changes. Electrospun camphosulfonic acid doped polyaniline-polystyrene (HCSA doped PANI-PS) fibers were also produced for glucose sensing measurements. Glucose oxidase (GOX), an enzyme, was immobilized on as-spun fiber surfaces prior to glucose sensing detection. Pristine H2O2 solution was used for testing the glucose sensing electrode composed of HCSA doped PANI-PS fibers. The cyclic voltammetry method was used to detect the redox currents for varied glucose concentrations at the oxidative potential of the glucose oxidation. The surface morphology before and after sensing measurements of as-prepared fibers for both types of sensors were investigated. Sensitivity comparison was performed between the fiber and film-type sensors as indicated by the slopes of humidity versus logarithm of resistance lines and glucose concentration versus redox current lines. Electrospun polyacrylonitrile (PAN) fiber precursor based carbon fiber (CNF) as well as electospun nickel (Ni) nanofiber-based mats were also produced and impregnated with epoxy resin. The electrical and mechanical properties of as-prepared nanofibers in the mat and short fiber filled epoxy nanocomposite forms were determined to demonstrate the effect of fiber aspect ratio and interconnecting network on those properties. Furthermore, the improvement of CNF conductivity was achieved by using in-situ silver (Ag)-PAN fibers as precursors, as well as by chemically coating Ag on CNF mat surfaces. For electrospun Ni nanofibers, Ag was chemically coated on fiber surfaces to prevent metal oxidation, and to increase conductivity. The characterization of samples was performed by using scanning electron microscope (SEM), Raman spectrometer, wide angle x-ray diffractometer (WAXD), Thermal gravimetric analyzer (TGA), Fourier transform infrared spectrometer (FT-IR), dynamic mechanical analyzer (DMA), voltmeter, and tensile tester. The effect of high thermal conductivity of CNF mat on curing reaction of epoxy nanocomposites was also studied by isothermal and dynamic experiments using DSC together with the gel content determination.

▼ Specific objective: Guided tissue regeneration (GTR) aims to regenerate the lost attachment apparatus caused by periodontal disease through the use of a barrier membrane. For the GTR procedures to be successful, barrier membranes are required to be present at the surgical site for an extended period of time (weeks to months). Synthetic membranes have the advantage of prolonged presence in a wound site; however, they do not actively contribute to wound healing. Biologic membranes are recognized by the host tissue and participate in wound healing but have the disadvantage of early resorption. Therefore, the goal of this study is to create and characterize a hybrid barrier membrane that contains biologically active fibrin matrix within a synthetic polymeric electrospun scaffold. Method: Fibrin matrices and fibrin-incorporated electrospun scaffold were created from fresh frozen plasma at three different centrifugation conditions 400g for 12 minutes, 1450g for 15 minutes and 3000g for 60 minutes. Following centrifugation, half of the membranes were crosslinked with 1% genipin. Biological stability of these scaffolds was evaluated by resistance to trypsin while their mechanical properties were characterized by MTS Bionix Uniaxial Tensile Testing System. Continuous data was analyzed by ANOVA to detect differences between groups (p=0.05). Results: The addition of an electrospun scaffold to the fibrin matrix led to improvements in the mechanical properties as evidenced by an increase in the modulus (p<0.0001), strain at break (p<0.0001) and energy to break (p<0.0001). The effect of crosslinking was marginal but not statistically significant to the mechanical properties of fibrin matrices or the fibrin incorporated scaffold. However, crosslinking did significantly increase resistance against enzymatic degradation by trypsin (p<0.0001). Lastly, centrifugation speeds at 400g and 1450g showed similar mechanical properties and biologic stability; meanwhile 3000g negatively impacted the properties of the scaffold. Conclusion: Fibrin-incorporated electronspun scaffold exhibits enhanced mechanical and biologic stability compared to fibrin matrices alone. Moreover, crosslinking improves the biologic stability of the novel biomaterial. All these characteristics of the fibrin-incorporated matrix make this membrane a potentially more ideal barrier for GTR procedures to enhance periodontal wound healing.

La filature par voie électrostatique consiste à dissoudre un polymère dans un solvant, puis soumettre cette solution à un champ électrostatique intense. Différents paramètres influencent l'obtention, la production et la régularité des nanofilaments obtenus. Parmi ces paramètres, il y a des paramètres physiques inhérents à la cabine de filage, des paramètres électriques et des paramètres liés à la solution. Pour obtenir des nanofilaments, la première étape est de déterminer le ou les meilleurs couples polymère-solvant ainsi que les conditions expérimentales optimales pour obtenir à la fois des produits homogènes et reproductibles. L'obtention de nanofilaments de caractéristiques mécaniques et de structures données est complexe et dépend à la fois de paramètres de filage, mais aussi des propriétés de la solution. Une des propriétés les plus importantes de la solution est sa viscosité. Il a donc été nécessaire d'étudier, pour différents couples solvant-polymère (PA, PAN, PLA, PHEA) leur comportement rhéologique. Ces études rhéologiques ont permises d'expliquer les morphologies des matériaux obtenus par la conformation macromoléculaire de la solution. Les non-tissés de nanofibres obtenus ont été caractérisés par Microscopie à Forces Atomiques (AFM), Microscopie Electronique à Transmission (MET) et à Balayage (MEE) pour les aspects morphologiques. D'autres caractérisations, thermique (DSC), spectroscopique (FTIR) et mécaniques (traction et indentation) ont complété la caractérisation de ces matériaux. A l'issue de l'étude précédente, les nanofibres ont été employées dans deux applications. (1) L'incorporation et la compatibilisation de nanorenforts à l'intérieur d'une matrice polymère (Polyacrylonitrile). L'influence sur les propriétés géométriques des nanofibres de façon globale, et plus finement, la morphologie de surface, ont été observées par une analyse AFM de nano-rugosité. (2) La réalisation à partir d'un biopolymère d'un guide tubulaire permettant la croissance cellulaire et la reconnexion de nerfs sectionnés. Il a fallu pour cela remplir un cahier des charges rigoureux en termes de dimensionnement, de structure, et de propriétés mécaniques.

Electrospinning is a process to produce the fibers in nano scale by injecting the polymer solution through a metallic needle to a high voltage electrical field. Different parameters affect the process production and regularity of obtained nano-web. Among these parameters, there are physical parameters depending on the electrospinning booth, electrical parameters and polymer solution properties. For nanofibers production, the first step is to determine the most efficient polymer-solvent pairs and the optimal experimental conditions for both homogeneous and reproducible products. Obtaining mechanical and morphological properties of nanofibers nonwowen is complex and depends on the electrospinning parameters, but also the solution properties. One of the most important properties of the solution is its viscosity. It was therefore necessary to study for the selected pairs (PA,…

▼ Electrospinning has been considered a versatile method for producing nanofibers, which have generated great interest for use in many areas, including those of tissue engineering and filtration, due to their high surface area to volume ratio and high porosity. Mechanical properties of these materials are important for these and other applications. Although much work has been carried out in the area of electrospinning technology over the past decade, little has been focused on the structure of electrospun webs and their mechanical properties. This work was undertaken to close a part of this gap existing in the literature. Using PEO as the polymer and water as the solvent, a series of electrospun webs were produced. The primary variables used were polymer concentration and time of spinning and properties measured were peak stress-peak strain, initial modulus and yield point. It was found necessary to adjust voltage and the distance between the needle and collector plate to get a stable Taylor cone, which was essential for forming uniform fibers. Three levels of concentrations, 8, 10 and 12.5% PEO were used to produce electrospun webs and these led to nanofibers of diameter 210nm, 325nm and 550nm, respectively. Increase in concentration resulted in decrease in stress and modulus values, and increase in strain values. The time of spinning was varied to simply vary the areal density of the web that was expected to have an influence on peak force; areal density was particularly an important input parameter for the model used for predicting the tensile properties of a web. The model to predict the tensile properties of web required single fiber stress-strain properties. Difficulty of conducting tensile test on single fibers required the use of an alternative way, tensile testing of aligned fiber bundles. Aligned fiber bundles were produced using collector strips separated with gap. For these fibers, effect of concentration and spinning distance on fiber morphology and mechanical properties were investigated. Concentration showed similar effect as found in the case of unoriented webs, with increase in concentration fiber diameter increased, and stress and modulus values decreased. With increase in spinning distance, fiber diameter decreased, and stress and modulus values increased. A mathematical model is developed and proposed for predicting the stress-strain behavior of electrospun webs. The analysis method used was the Ã¢â‚¬Å“Force methodÃ¢â‚¬Â . Peak stress values were predicted using single fiber stress-strain properties in conjunction with the model. Predicted values of peak stress matched closely with the measured values within a correction factor of less than two. Reasons are given for the small differences noted between the measured and predicted values. The results noted in the measured values of peak stress and the difference found between the predicted and the measured values suggest that the fibers in the electrospun webs are bonded to some extent at the cross-over points. This leads to the suggestion that the… Advisors/Committee Members: Dr. Jeffrey Ray Thompson, Committee Member (advisor), Dr. Bhupender S Gupta, Committee Chair (advisor), Dr. Hechmi Hamouda, Committee Member (advisor).

▼ Nanoparticles have been extensively studied in environmental research because of their great impact on human health and the environment. Airborne particles are recognized as the second largest risk factor for non-communicable diseases worldwide in 2018 after tobacco smoking, which also is associated with inhaled particles. Intermediate particles, which bridge gas molecules and aerosol particles, are a major fraction of environmental airborne particles. However, no regulations are available for controlling nanoparticles, despite that such regulations for the nanoparticle emissions are needed for global health and wellbeing. Understanding the behavior of intermediate particles and their separation from the air are important to the policy-making and technology development for the protection of human health and the environment. Separation and deposition of entities underlie the adsorption and filtration processes. Adsorption is a well-known method for the separation of molecules, and filtration is for the separation of airborne particles. Despite the efforts on the theoretical analyses of adsorption and filtration, a holistic framework for the separation of a whole range of entities is needed to unify their mechanisms of separation. This research aims to develop a comprehensive model for the separation of entities including gas molecules, intermediate nanoparticles, and regular nanoparticles, from the air. The specific contributions to the field include 1. Modeling the transport of entities to the nanofiber surface by considering both convective diffusion and interfacial interaction due to the van der Waals force. 2. Modeling the deposition of intermediate nanoparticles onto clean fibers. 3. Modeling the effects of time and concentration on the deposition of all entities onto nanofibers. The first model calculates the rate of particles, transported to the fiber surfaces. The rate of collision based on convective diffusion and interfacial interactive diffusion is calculated by boundary layer analysis around a single fiber. In addition to airflow, the entities are under another streamflow due to the van der Waals force. This model is validated using experimental data from the literature for nanoparticles. The second model is developed by considering the interfacial interaction on the adhesion of intermediate nanoparticles on clean fiber. Brownian diffusion, which has been considered as the mechanism of filtration of sub-100 nm particles, is not affirmative for intermediate nanoparticles. In this model, the interfacial interaction plays an important role in the adhesion and detachment of intermediate nanoparticles. Adhesion probability is determined as a function of particle size and interfacial interaction energy. The third, kinetic model is an expansion of the second one by considering surface coverage, which depends on time and particle concentration. This kinetic model applies to both gas molecules, and intermediate nanoparticles, by considering their surface coverage. Concentration and time may play an…

▼ Microfluidic biosensors which incorporate both sample preparation and analyte detection, also referred to as lab-on-a-chip (LOC) devices, are a promising means of providing low cost, rapid, and portable analyte detection in point-of-care, rural, and developing world applications1- 3 . However, despite numerous reports of LOC devices capable of detecting a range of clinical analytes1-3, there are several key challenges that face the development of true LOC devices. First, due to the small size of these miniaturized systems, it is often necessary to significantly concentrate the sample volume to the nL-[MICRO SIGN]L range 4. Additionally, samples must be purified to remove particulates and impurities that may impede analyte detection. Finally, fluid flow in microfluidic devices is generally laminar, which limits the amount of fluid mixing that occurs within the channels5-7. Because rapid fluid mixing is typically required to facilitate chemical reactions and ensure access of analytes to functional surfaces within the microchannels, micromixers need to be incorporated into the design of a LOC device. This research aims to address the need for both better sample preparation and fluid mixing within microfluidic assays through the use of functionalized electrospun nanofibers. Electrospinning is a fiber formation process in which electrical forces are used to form ultrathin fibers from viscous polymer spinning solutions8. The nonwoven fiber mats produced during electrospinning are characterized by extremely large surface-area-to-volume ratios and high porosities. Additionally, electrospun nanofibers can easily be functionalized either through the inclusion of nanoscale materials into the polymer spinning dope, or through post-spinning modifications. In this work, positively and negatively charged poly(vinyl alcohol) (PVA) nanofibers were created through the addition of hexadimethrine bromide (polybrene) and poly(methyl vinyl ether-alt-maleic anhydride) (poly(MVE/MA), respectively, into a 10% w/v PVA spinning solution. Additionally, larger diameter polystyrene (PS) microfibers with a range of morphologies were spun using 12.5, 15, and 17% w/v PS spinning solutions. Previously, gold microelectrodes patterned onto poly(methyl methacrylate) (PMMA) were used to incorporate the nanofibers into microfluidic channels9,10. However, in this work, fibers were bonded into microchannels without the use of a gold electrode, resulting in simple, inexpensive device fabrication. Both PVA and PS fibers were spun onto metal collector plates and manually transferred to pieces of PMMA that had undergone UV-Ozone treatment. In order to produce nanofiber mats with uniform fiber distributions along their height, thin nanofiber mats were stacked together to create multilayered mats 11,12. Positively charged PVA mats were shown to successfully bind and concentrate E. coli cells, while negatively charged PVA mats repelled the cells and were used to minimize nonspecific retention within the channels. The 3D morphology of the PVA nanofiber mats was… Advisors/Committee Members: Baeumner,Antje J (chair), Kirby,Brian (committee member), Frey,Margaret W (committee member).

▼ Los alimentos ricos en carbohidratos y que son sometidos a altas temperaturas para su elaboración, generan compuestos potencialmente tóxicos, como lo es la acrilamida, la cual es estudiada como cancerígeno y genotóxico para humanos (2A), siendo el aminoácido asparagina su mayor precursor. El objetivo de este estudio fue elaborar pan tipo hallulla con adición de asparaginasa para obtener niveles reducidos de acrilamida, conservando sus características sensoriales originales. El contenido de acrilamida se determinó en un Cromatógrafo de Gases -Espectrómetro de Masas (GC-MS), en las muestras de pan por triplicado. Se determinó que el contenido de acrilamida presente en el pan control es 108 μg/kg. Se evaluó un rango de concentración de 20-300 ppm de enzima asparaginasa/ kg de harina, siendo el rango óptimo de 100 y 150 ppm de enzima/ kg de harina, pues se reduce la cantidad de acrilamida entre 80% y más del 99%, respectivamente. Mediante un panel sensorial entrenado se evaluó la calidad sensorial y perfil descriptivo del pan elaborado con enzima asparaginasa (300 y 150 ppm de enzima/ kg de harina) respecto al pan de la formulación control. Los resultados muestran que la calidad sensorial fue calificada como grado 1, sin diferencias significativas (p≤0,05) entre el pan control y el pan elaborado con asparaginasa, para los atributos color, apariencia/forma, aroma, sabor y textura. Resultado similar presentó el perfil descriptivo, pues no hubo diferencias significativas (p≤0,05) entre muestras, para los descriptores color corteza, aroma fermentado, aroma tostado/quemado, dureza al tacto, elasticidad miga, dureza en boca, sabor fermentación/levadura y sabor tostado. La elaboración de pan tipo hallulla con la incorporación de la enzima asparaginasa resultó ser una medida adecuada para mitigar la acrilamida en el pan final, obteniendo una reducción casi completa de acrilamida y conservando las características sensoriales originales del pan; Foods rich in carbohydrates cooked at high temperatures generate potentially toxic compounds such as acrylamide, which is studied as carcinogenic and genotoxic compound to humans (2A) and whose main precursor is the amino acid asparagine. The aim of this study was to develop hallulla bread with added asparaginase in order to reduce the levels of acrylamide after baking while preserving its original sensorial characteristics. Acrylamide content was determined by gas chromatography-mass spectrometry (GC-MS) in the bread samples in triplicate. It was determined that the level of acrylamide present in the control bread was 108 μg/kg. A concentration range of 20-300 ppm of asparaginase enzyme/ kg of flour was evaluated, with the optimum range of 100 to 150 ppm of enzyme/ kg of flour, reducing the amount of acrylamide between 80% and 99%, respectively. A trained panel assessed the sensory quality and descriptive profile of bread made with enzyme asparaginase (300 and 150 ppm enzyme/ kg of flour) and the control bread formulation. The results showed that the sensory quality was rated…

▼ TiO2 and MgO were investigated as self-decontaminating catalysts on a fibrous substrate. A photo-oxidation mechanism with UV energy resulting in strong oxidation by TiO2 was demonstrated by degradation of a carbamate pesticide. In contrast, MgO functioned through surface destructive adsorption and thus did not require exposure to UV radiation for self-decontamination to occur. Regarding to the effect of fiber morphology, two types of morphology were studied: Core/sheath fiber and continuous porous fiber structure were formed in electrospinning. In the core/sheath approach by coaxial spinning, a higher density of nanoparticle distribution in the surface region was observed when compared with the uniaxial approach, which means the probability of interaction between TiO2 and toxin increased. The core/sheath structure with a higher particle concentration in the sheath provided more rapid initial degradation of toxin and the photocatalytic reaction of core/sheath morphology showed second-order behavior. It was also observed that the fibers containing higher content of TiO2 degraded more pesticide for both uniaxial and coaxial fibers. Aside from the selective location of nanoparticles to the fiber surface, interconnected porous morphology was studied. With varying the ratio of solvents, different morphologies were observed in electrospun fibers. A polymer solution consisting of An/Ac 60/40 and 15 wt % of CA/PEO 60/40 (80/20 in moles) enabled the highest degree of continuity (0.77) of PEO phase in CA matrix during the electrospinning. The interconnected intra-fiber pores (89 nm width) and large surface area (21.8 m2/g) were observed at the electrospun fiber fabricated with the above composition. A catalyst incorporated substrate of the nanochanneled fiber contained MgO was investigated as a methyl parathion removal membrane. In both a soaking test and a membrane filtration, the MgO loaded highly channeled fiber was observed to remove more amount of MP, which resulted from the physical adsorption and destructive adsorption. MP was suggested to be adsorbed and removed from solutions by the exposed MgO particles in fiber and the adsorption to porous fiber. The advantage of the channeled morphology over the conventional regular surface in fiber was showed up in a membrane filtration process. SEM, DSC, TGA, XRD, a BET instrument, and HPLC were used to confirm the morphology, chemistry, and removal performance. Advisors/Committee Members: Obendorf, Sharon Kay (chair), Joo, Yong L.

ENGLISH ABSTRACT: Grapes are lost annually due to spoilage by Botrytis cinerea. Botrytis cinerea is currently controlled using fungicides and SO2 fumigation in storage rooms but with limited success. Although these techniques have been used for decades they have been associated with numerous of disadvantages. Fungicides are restricted from being used during storage due to legislation and toxicity of the fungicides present on the surface of the berries. SO2 fumigation does not kill the dormant infections present inside the grape tissue and if the SO2 concentration is too high the berries are damaged. During this study two different polymer nanofibrous platforms was synthesized in an attempt to prevent the rotting effect of B. cinerea. The first polymer was modified to yield a polymer with a positively charged quaternized nitrogen moiety, which was subsequently reacted with sodium metabisulfite through an ion exchange process. The modified polymer was electrospun into nanofibrous mats for the benefit of the nanofibers’ high available surface area. A further functionalization was done to increase the quantity of sodium metabisulfite on the surface of the polymer nanofibers. Sodium metabisulfite salt released SO2 gas upon reaction with water vapour present in the atmosphere which resulted in the inhibition of conidial germination of B. cinerea. The second polymer was synthesized and then electrospun into polymer nanofibrous mats followed by chemical modification of the electrospun polymer nanofibers. This post-electrospun modification resulted in the covalent attachment of a fungicide-derivative to the surface of the polymer nanofibers. The fungicide-derivative showed excellent inhibition of B. cinerea mycelium growth. Anti-fungal studies were conducted using the two modified polymer nanofibrous mats against B. cinerea to evaluate these nanofibrous surfaces as B. cinerea inhibiting membranes. Results indicated that B. cinerea conidial germination and mycelium growth were successfully inhibited.

AFRIKAANSE OPSOMMING: Druiwe bederf jaarliks weens die verrottende effek van die fungi Botrytis cinerea. Botrytis cinerea word tans beheer deur gebruik te maak van swamdoders en swaweldioksied (SO2) besproeiings in stoorkamers, maar met beperkte sukses. Alhoewel hierdie tegnieke al vir dekades in gebruik is, word dit geassosieer met verskeie probleme. Die gebruik van swamdoders word in stoorkamers verbied, weens die moontlike skadelike inname daarvan deur die mens aangesien die swamdoders op die druiwe se oppervlakte teenwoordig is. SO2-gasbesproeiings maak nie dormante infeksies binne-in die druiwe self dood nie en indien SO2 -konsentrasies te hoog is kan dit die druiwe beskadig. Tydens hierdie studie is twee verskillende polimeer-nanoveselplatforms gesintetiseer met die doel om die verrottende effek van B. cinerea te voorkom. Die eerste polimeer is aangepas met ’n primêre amienverbinding met die doel dat dit deur ‘n opvolgende modifikasiereaksie verander om sodoende ’n polimeer met ‘n kwatenêre ammoniumgroep te…
