Effects of a nanometer-size, reactive polyhedral oligomeric silsesquioxane (POSS) on a thermoset’s polymerization kinetics and dielectric relaxation have been investigated by using differential scanning calorimetry (DSC) and dielectric spectroscopy. Four amines, hexylamine (HA), ethylene diamine (EDA), isophorone diamine (IPDA), and diethylene triamine (DETA) were used to crosslink epoxy resin DGEBA and a multi functionalized -glycidyl POSS. The polymers formed ranged from POSS-free to POSS-only network structure, while maintaining an equal ratio of reactive groups. Calorimetric studies of stoichiometric DETA and IPDA samples performed by ramp-heating showed that the polymerization kinetics increased with low POSS content, but progressively decreased upon further addition, and the POSS-only mixtures reacted the slowest. The same pattern of changes in the rate of polymerization was observed by isothermal polymerization of the DETA mixtures. The results have been interpreted based on changes in viscosity and diffusion coefficients according to the Stokes-Einstein and Smoluchowski equations. Furthermore, isothermal polymerization of stoichiometric DETA and EDA samples showed that the extent of reaction increased with POSS, indicating that it might be easier to form a higher crosslinked thermoset with higher amounts of POSS. Non-isothermal polymerization of POSS-IPDA mixtures was also investigated under off-stoichiometric conditions. Unlike the reaction mechanisms of non-stoichiometric DGEBA-IPDA mixtures, a significant difference in reactivity of primary and secondary amines in the POSS-IPDA reaction was not observed. Dielectric relaxation studies were performed in real time during polymerization. The distribution of relaxation rates increased with an increase in POSS, and the duration of polymerization required to reach a specific relaxation time increased. Furthermore, the time at which the dielectric loss minimum and peak occurred increased with POSS, however, when only POSS was reacted with the amine, an a-relaxation peak was not observed. A frequency-dependent increase in permittivity during polymerization was observed with the POSS-only EDA, DETA, and HA samples, and a corresponding change in the loss was not detected. It was attributed to a structure-dependent increase in interfacial polarization. Although not related to the polymerization study, work done on the residual entropy of glasses is included here. To help resolve the controversy of the residual entropy of glassy materials, specific heat data taken from the literature were analyzed. The changes in entropy of a glass on cooling and heating paths were determined, and it was found that the upper and lower limits of entropy differed by no more than 2 %. This showed that although the thermodynamic path through the glass transition is irreversible, this irreversibility has a negligibly small effect on determining the entropy.

The development of all-electric or plug-in hybrid vehicles requires the use of advanced energy storage devices with high power. Dedicated for energy storage, electrochemical supercapacitors (ES) offer the advantage of high power density. High power ES can provide load-leveling for batteries and fuel cells during starting, acceleration, hill climbing and braking. ES are important for reducing cycling of batteries, thus extending their lifetime by energy storage and delivery during fast transient operations such as in braking (storage) or start up and acceleration (supply). The interest in polypyrrole (PPY) for the application in ES is attributed to the high specific capacitance (SC) of this material. The possibility of PPY deposition on stainless steel substrates is important for the practical applications of PPY films in ES, using low cost stainless steel current collectors. The important task is to avoid anodic dissolution of the substrates during PPY electropolymerization. Polypyrrole (PPY) films were electrochemically deposited on stainless steel substrates or Ni plaque from aqueous pyrrole solutions containing anionic additives. The method resulted in the formation of adherent and uniform films. The deposition yield was investigated at galvanostatic conditions. It was found that anionic additives can be used for the dispersion of multiwall carbon nanotubes (MWCNTs) and fabrication of composite PPY–MWCNT films. The deposition yield was studied under galvanostatic conditions. The mechanism of PPY–MWCNTs deposition was discussed. The incorporation of MWCNTs into the PPY during electropolymerization resulted in the formation of porous films. The films were investigated for the application in electrodes of electrochemical supercapacitors. Electrochemical testing in the 0.5M Na₂SO₄ electrolyte solutions showed a capacitive behaviour in a voltage window of -0.5 to +0.4 V versus a saturated calomel electrode. The results indicated that the PPY–MWCNT films deposited on the stainless steel and nickel plaque substrates are promising electrode materials for ES.

▼ Polymer diffusion and matrix morphology are investigated in polymer nanocomposites (PNCs). Using elastic recoil detection, tracer diffusion coefficients (D) of dPS and dPMMA are measured in PNCs containing polystyrene (PS) with phenyl-capped (Ph) silica, and poly(methyl methacrylate) (PMMA) with hydroxyl-terminated (OH) silica nanoparticles (NPs), respectively. As NP volume fraction increases or NP size decreases, polymer diffusion slows down. Moreover, D plotted relative to diffusion in a pure PS matrix (i.e., D/D0) falls on a master curve when plotted against the interparticle distance of NPs relative to the tracer radius of gyration, ID/2Rg. This slowing down with increasing confinement is consistent with an entropic barrier model which captures conformational entropy loss as macromolecules squeeze through a bottleneck (i.e., array of NPs). To investigate polymer-NP interactions, tracer diffusion of dPMMA is investigated in PMMA:OH-NP. Because of the attraction between dPMMA segments and OH groups on the NPs, tracer diffusion is slower than in the dPS system which involve weak interactions with the phenyl grafted NPs. Third, tracer diffusion is investigated in a bicontinuous structure. By adding NPs that segregate and jam at the interface during phase separation, a novel processing method was developed to prepare discrete or bicontinuous structures of PMMA:poly(styrene-ran-acrylonitrile) (SAN) films. A jamming map of the morphology summarizes the NP concentration and film thickness to produce either morphology. Diffusion of dPMMA in this bicontinuous structure is slower than in PMMA, a result attributed to the tortuosity of the continuous PMMA matrix phase. In summary, macromolecular diffusion has been investigated in PNCs as a function of tracer molecular weight and matrix properties including NP volume fraction, NP size, and NP interactions with tracer molecule. Understanding how to disperse NPs at high loadings is crucial for fabricating polymeric devices including membranes for fuel cells and organic solar cells. These diffusion studies are also practically important for selecting processing conditions to prepare hybrid materials. Finally, the bicontinuous morphology is attractive for applications requiring high interfacial area such as organic solar cells, membranes, catalysis, and fuel cells.

▼ The methodology towards the creation of nanoscale polymeric objects by way of the folding of single polymer chains has been enjoying success in the field of polymer chemistry and materials science. By synthesizing polymer chains with built in functionality either through functional side groups, or direct incorporation into the polymer backbone, polymer chemists are able to fold single polymer chains onto themselves through a broad range of covalent and non-covalent interactions in dilute solution. These compact, nano-sized objects can now be used in a wide arrange of functions and applications. The aim of this dissertation is to provide first, a comprehensive overview of the recent advances and success enjoyed by this field and second, to showcase some of the various routes towards the dynamic and modular creation of these single-chain polymer nanoparticles (SCNPs). Chapter 2 of this work discusses the use of dynamic covalent cross-linking chemistry via reversible disulfide bridges in the folding and unfolding of SCNPs. Through the use of triple detection size-exclusion chromatography (SEC) it was shown through changes in retention time, a phenomena indicative of hydrodynamic volume, a polymer was being folded into compact SCNPs and then unfolded and refolded via redox chemistry. Chapter 3 explores the design of polymers that had various different cross-linkable moieties incorporated into the monomer side units. By having cross-linkable moieties that can undergo different chemical cross-linking reactions (i.e thiol-yne click reactions, epoxide ring-opening reactions, activated esters), a modular approach towards the folding and subsequent functionalization of SCNPs is created. Looking to design a system with a greater degree of control over the modular functionality, chapter 4 investigates the use of norbornene imide monomers containing pentafluorophenyl activated esters with varying methylene spacer unites between the polymerizable olefin and the activated ester. It was here that an unexpected phenomena was observed; the doping effects of fluorinated aromatic hydrocarbons (FAHs) on second and third generation Grubbs’ catalysts. This chapter aims to shed some light on this subject. Finally in chapter 5 an additional click-chemistry reaction is observed to take place with pentafluorophenyl methacrylate. Thiol-para fluoro click reactions are used to react with the pentafluorophenyl activated esters, while still leaving the ester moiety reactive towards primary alkyl amines.

▼ Due to increasing demand of energy and the limited supply of the main energy sources (coal, oil, uranium etc.), scientists are looking for the alternative energy sources which are renewable, low cost, easy to manufacture, abundant, light weight and efficient. Photoelectrochemical (PEC) cell has the potential to convert and store solar energy into chemical bonds through the splitting of water into molecular oxygen and hydrogen. Hematite (α-Fe2O3) is a promising photoanode material due to its chemical stability in aqueous mediums, suitable energy band gap for light harvesting, low cost and environment friendliness. However, its performance for water oxidation is limited by low carrier concentration and poor electronic properties that lead to high overpotential for water oxidation and low solar to hydrogen conversion (STH) efficiency. Nanostructuring, elemental doping, surface passivation layers and deposition of co-catalyst layers are the possible ways to improve the performance of hematite. Here, I report a comprehensive approach (nanostructuring, doping and surface passivation) to improve the performance of hematite photoanode. A substantial improvement in the photoelectrochemical (PEC) performance of hematite (α-Fe2O3) has been observed by doping with manganese (Mn). Fe2O3 nanorods sample with 5% Mn treatment show a photocurrent density of 1.6 mAcm-2, (75% higher than that of pristine Fe2O3) at 1.23 V vs. RHE and a plateau photocurrent density of 3.2 mAcm-2 at 1.8 V vs. RHE in 1M NaOH electrolyte solution (pH 13.6). Consequently, we established a simple method to passivate the surface defects of hematite photoanode for water splitting with a core-shell hematite (α-Fe2O3) nanorods system. Electrochemical impedance spectroscopy (EIS) characterization reveals passivation of the surface defects by the highly crystalline hematite shell layer, which enhances the charge injection. In pristine hematite, more holes are accumulated on the surface and the charge transfer to the electrolyte occurs through surface states, whereas in core-shell hematite photoanode, the majority of hole transfer process occurs through the valence band. As a result, the photoactivity of the core-shell nanorods: 1.2 mAcm-2, at 1.23 V vs. RHE, is twice that of pristine hematite nanorods. After establishing the Mn doped and core-shell hematite systems, we employed intensity modulated photocurrent spectroscopy (IMPS) to understand their charge dynamics for PEC water splitting. The information about the photogenerated holes transfer at the electrode/electrolyte interface for water oxidation and losses due to electron-hole recombination via surface states will help to understand the limiting factors in hematite photoanodes. We observed a two-fold increase in charge transfer rate upon Mn doping, and more than one order reduction in charge recombination rate in core-shell hematite as compared to the pristine hematite photoanode. These results indicate that both Mn doped and core shell hematite photoanodes enhance the PEC performance, although the…

▼ Electronic instruments that operate using organic semiconductors are already available on the market. Organic light emitting diodes are in numerous displays of mobile phones or some TV sets. Organic solar cells with efficiency larger than 5% are produced by small start-up companies. Organic field effect transistors have achieved charge mobilities larger than that of amorphous silicon. Therefore it is justified to ask for the intrinsic limit of organic semiconductors and how to improve the physical properties of organic semiconductors. This study focuses on the most perfect form of solid state made from an organic semiconductor, on organic single crystals. High defect concentrations and grain boundaries cause hindrance to the charge carrier‘s transport. Relatively long radiative decay of excitons can be achieved in high quality Light Emitting Organic Field Effect Transistors (LEOFET) built from high charge carrier mobility materials. Therefore, using high quality molecular single crystals for fundamental research in organic electronics will be valuable in pushing forward the cutting edge of these technologies. To study organic semiconductors, single crystals of numerous organic semiconductors have been produced. Furnaces with high precision temperature control were built for growing of high quality single crystals. The high quality of a single crystal was defined in terms of high crystallinity, high purity and molecularly smooth crystal surface. Numerous high quality mono-component and charge-transfer (CT) binary-component molecular single crystals have been grown using solution phase and gas phase methods. Powder X-ray diffraction (PXRD), single crystal X-ray diffraction (SCXRD) and cross-polarized light microscopy (CPLM) were done to characterize the crystallinity and the crystal phase of the single crystals. High performance liquid chromatography (HPLC), liquid chromatography mass spectrometry (LCMS), Matrix-assisted laser absorption/desorption mass spectrometry (MALDI-ToF-MS), photoluminescence (PL) and attenuated reflection fourier transform infrared spectroscopy (ATR-FTIR) were used to study the purity of the single crystals. Atomic force microscopy (AFM) was used to investigate the surface roughness of the single crystals. The bandgap of the molecular single crystals could be reduced by growing CT binary-component molecular single crystals. High conductivity molecular single crystals could be attained with peri-substituted dichalcogenide polycene, such as tetrathiotetracene (TTT). The highest charge carrier mobilities of holes and electrons were measured for rubrene, tetracene, F16CuPc and few more single crystal FETs. Yet, the limit of the mobility of organic materials is still a mystery. It was found that the measured mobilities from the single crystal FETs do not represent the intrinsic mobility of the materials. The measured mobility highly depends on the surface states of the single crystals which are largely affected by the fabrication process of the single crystal FETs. The physical properties of…

This experimental research thesis describes the combination of conjugated polymers and carbon nanotubes with the fields of electrophoretic deposition (EPD) and organic solar cells. Prior to these contributions, soluble conjugated polymers and carbon nanotubes that have been functionalized by them had not yet been deposited by EPD from solution or by using non-toxic solvents. Additionally, EPD had not yet been utilized to deposit the active layer in a solid organic photovoltaic device. The EPD of soluble conjugated polymer functionalized carbon nanotubes from non-toxic solvents was achieved through an iterative process of experimentation and technique refinement. The developed EPD technique utilized the high pH region at the cathode substrate to neutralize positively charged weak polyelectrolytes macromolecules. Their functional groups were protonated using a minimized amount of acetic acid which also enabled their solubility. Deprotonation of the quaternary ammonium functional groups rendered them neutrally charged and insoluble tertiary amines. This mechanism facilitated the formation of coatings that were predictable and uniform in appearance and thickness. Control over coating thickness was demonstrated by coatings spanning 100 nm to 10 μm. These coatings were produced by adjusting the applied voltage, solution concentration, and tuning the deposition duration. Techniques for the fabrication of a photovoltaic device using an active layer produced by EPD were established though modifications of general organic photovoltaic device fabrication procedures. These modifications involved redesigning the photolithographic ITO etching pattern, adding an insulating barrier strip, thickening the aluminum electrode layer, and switching the top buffer layer from LiF to BCP.

Nanomaterials have been heavily studied in the past two decades. Previous findings have demonstrated that the characteristics of nanocomposites and the performance of nanomaterial-based devices are both determined by the interfacial characteristics of the nanomaterials. However, there are still some remaining challenges from interfacial characteristics to device applications, which are specified as follows: the difficulty in identifying the interfacial contacts of nanostructured surfaces, the instability of nanocomposite surfaces, and the under-researched mechanism of the correlation between interfacial characteristics and the performance of devices. Therefore, the main theme of this thesis is to investigate the interfacial contacts of nanostructured solid-liquid interfaces by direct observation, and to develop a stable nanocomposite based on which the direct observation of the interfacial contact can be better conducted, and to eventually investigate the effect of interfacial contacts on the performance of organic solar cells. As the previous identification of the solid-liquid interface is limited to a microscale range, a direct method of tracing the different wetting states of water was developed, on nanostructured surfaces. This method provided an answer to a long standing question of, whether there is a transition from Wenzel to Cassie states in the sliding angle drop on nanocomposite thin films. In order to complete the observation of the wetting states of water, a stable superhydrophobic nanocomposite thin film with hierarchical structure was developed. Furthermore, with the knowledge of identifying the wetting states and the preparing procedures of the nanocomposites, a surfactant-free small-molecule nanoparticle organic solar cell with a much improved fill factor was developed by spin coating. The inverse correlation of series resistance and parallel resistance was discovered, due to the morphology change and the variation of the charge carrier concentration near the donor-acceptor interface in small-molecule organic solar cells.

▼ Electrochromism is a phenomenon that some materials involving reversible color changes through redox reactions under electrical stimulus. This PhD work is aimed at developing hybrid materials based on conjugated polymers (CPs) and transition metal oxides (TMOs), which combine the advantages of both materials and exhibit enhanced electrochromic properties, and understanding the underlying mechanisms. Tungsten trioxide (WO3) and poly(3,4-ethylenedioxythiophene) poly(styrene sulfate) (PEDOT:PSS) or its derivatives were employed to produce hybrid EC materials and devices. Firstly, the hybrid EC materials based on WO3 nanoparticles (NPs) and PEDOT:PSS were synthesized through the layer-by-layer (LBL) assembly method. Polyethylenimine (PEI) was applied to promote the electrostatic force between the two components. Single component films, namely PEDOT:PSS and WO3-NP films, were also fabricated as reference films through the same method. The hybrid films exhibit enhanced EC properties, especially the coloration efficiency (117.7 cm2/C), compared with the reference films. The enhancement may be attributed to the efficient charge transfer process between components, since the hybrid film exhibit enhanced electrical conductivity during switching as verified by the scanning electrochemical microscopy (SECM). According to literature and SECM results, the WO3 films experience conductive-to-nonconductive transition as applied potentials go from positive to negative, while the PEDOT:PSS presents high conductivity at its oxidized state. Therefore, in the hybrid system, the synergistic interactions between components promote the enhanced charge transfer process, resulting in improved EC performance. However, the nonconductive PEI layers involved may prohibit the redox reactions and the charge transfer process in the hybrid system, which would lower the EC performance. Secondly, to further improve the EC performance, the hybrid films based on WO3 and PEDOT:PSS were synthesized by one-pot sequential electrodeposition method without any PEI component. Single component films of same thickness were also produced as reference films. Compared with the reference films, the hybrid films exhibit significantly improved EC properties, especially the optical contrast (47%) and electrochemical stability. It’s resulted from the simultaneous switching and synergistic interactions of two components. The morphology and structure of the hybrid films can be manipulated through tailoring the electrodeposition parameters to enlarge the interfacial area, leading to efficient interactions between the components. Thirdly, the charge-balancing dopant PSS involved in the aforementioned hybrid systems is an electrical insulator, which may block the charge transfer process between WO3 and PEDOT, and lower the EC performance. Poly(4-(2,3-dihydrothieno[3,4-b]-[1,4]dioxin-2-yl-methoxy)-1-butane sulfonic acid (PEDTS) is a self-doped PEDOT derivative bearing a sulfonate group in each repeat unit. It was employed to replace PEDOT:PSS in the hybrid systems. A hybrid…

▼ Free-standing ultra-thin films and micro to nanoscale fibers offer a unique geometry in which to study the dynamics of thin film stability and polymer chain dynamics. By melting these films and investigating the subsequent processes of hole formation and growth, and fiber thinning and breakup, many interesting phenomena can be explored, including the nucleation of holes, shear-thinning during hole formation, finite-extensibility of capillary thinning viscoelastic fibers, and confinement effects on entanglement of polymer chains. Free-standing films in the melt are unstable and rupture due to instabilities. The mechanism of membrane failure and hole nucleation is modeled using an energy barrier approach which is shown to capture the dependence of hole nucleation on thickness. The formed holes grow exponentially and are found to grow under a shear thinning, nonlinear viscoelastic, high shear strain regime. These holes impinge upon each other to form suspended fibers. The fibers thin according to a model for the elasto-capillary thinning of the suspended viscoelastic fluid filaments. Monitoring fiber thinning allows for the acquisition of rheological properties as well as the transient, apparent extensional viscosity giving insight into strain hardening and eventual steady-state extensional viscosity. The decay and breakup of these fibers and their interconnected branched structure indicates the effects of confinement on chain entanglement in ultra-thin films. A transition below a critical film thickness, comparable to the dimensions of a polymer chain, shows drastically reduced interchain entanglements and a remarkably faster breakup of suspended fibers. The processes of fiber formation from the melting of ultra-thin films are explored in high detail and produce a new technique for the investigation of rheological and material properties, confinement effects, and the dynamics of thin films and polymer chains.

▼ A promising solution to address the present-day energy crisis is photovoltaic technology. Currently, the market is dominated by inorganic-based materials such as silicon, III-V semiconductors, CIGS, etc. Despite their technical maturity, the energy generated from these devices is still low. This is partially due to the high production cost of these materials. Therefore, the search for next generation photovoltaic technologies that utilize earth-abundant elements with low-cost production processes has been an intensive research area.Using solution-processable organic polymer semiconductors, polymer solar cells provide an opportunity to efficiently generate energy from sunlight at a reasonable cost. This is due to the ease of synthesis/modification of organic molecules and polymers compared to that of inorganic materials, the easily scalable solution-based fabrication process, and the use of cost-effective, environmentally friendly carbon-based elements. Owing to the vast research efforts over the past decade, the power conversion efficiencies of single- and multi-junction polymer solar cells have recently surpassed the 10% milestone.During this progression, materials development, driven by the desire to overcome the constraint of P3HT, has played a very important role in advancing the technology. To date, hundreds of photovoltaic polymers have been made through different combinations of conjugated building blocks and suitable functional groups. As a result, several state-of-the-art polymers, such as PTB7, PDPP3T, PBDTDPP and PffBT4T, have shown impressive performance. In order to keep this momentum going, further improvements and deeper insights into materials’ property are certainly needed. In this dissertation, we particularly focus on improving the properties of several state-of-the-art photovoltaic polymers by resolving their shortcomings using innovative organic synthetic approaches. It is demonstrated that the materials’ optoelectronic property as well as their fabrication process can be alternated through chemistry modification at a molecular scale, that is, by molecule engineering. This study paves a way not only to achieve high performance polymer solar cells, but also to provide novel synthetic strategies for researchers in the field to further push the boundaries of polymer solar cell technology in the future.

▼ The research presented in this dissertation focuses on the design and synthesis of novel hybrid conjugated polymer materials using two different approaches: 1) inorganic/organic hybrid semiconductors through the incorporation of carboranes into the polymer structure and 2) the modification of surfaces with conjugated polymers via grafting approaches. Hybrid conjugated polymeric materials, which are materials or systems in which conjugated polymers are chemically integrated with non-traditional structures or surfaces, have the potential to harness useful properties from both components of the material to help overcome hurdles in their practical realization in polymer-based devices. This work is centered around the synthetic challenges of creating new hybrid conjugated systems and their potential for advancing the field of polymer-based electronics through both greater understanding of the behavior of hybrid systems, and access to improved performance and new applications. Chapter 1 highlights the potential applications and advantages for these hybrid systems, and provides some historical perspective, along with relevant background materials, to illustrate the rationale behind this work. >Chapter 2 explores the synthesis of poly(fluorene)s with pendant carborane cages. The Ni(0) dehalogenative polymerization of a dibromofluorene with pendant carborane cages tethered to the bridging 9-position produced hybrid polymers produced polymers which combined the useful emissive characteristics of poly(fluorene) with the thermal and chemical stability of carborane cages. The materials were found to display increased glass transition temperatures and showed improved emission color stability after annealing at high temperatures relative to the non-hybrid polymer. The design and synthesis of a poly(fluorene)-based hybrid material with carborane cages in the backbone, rather than as pendant groups, begins in chapter 3. Poly(fluorene) with p-carborane in the backbone is synthesized and characterized, and the material is found to be a high MW, soluble blue emitter which shows a higher glass transition temperature and greater stability than a non-hybrid polymer. UV absorbance and fluorescence spectroscopy indicated some electronic interaction between the conjugated polymer and the cages, but they did not appear to be fully conjugated in the traditional sense. Chapter 4 describes the design, synthesis, and characterization of poly(fluorene) with o-carborane in the backbone. Profound changes in the behavior of the polymer, from its polymerization behavior to its emission characteristics, were observed and their origins are discussed. Experiments to explore the nature of the cage/polymer interactions were performed and possible applications which take advantage of the unique nature of the o-carborane hybrid polymer are explored and discussed. Hybrid conjugated polymer materials via grafting approaches to surfaces and surface modification are discussed starting in chapter 5. The synthesis of a… Advisors/Committee Members: Kenneth R.

▼ Fossil fuel resources are being used today for most of humankind’s energy and chemical/material needs. The inevitable demise of these resources has created significant interest in the field of biomass and particularly, lignin valorization. As the world’s second most abundant polymer, more than 98% of the annually produced lignin is under-utilized either as an on-site heat source, or as landfill. Thus, finding practical approaches to modifying this inexpensive sustainable resource into materials of high value can be the next leap in lessening the dependence on fossil fuel resources and thus, developing a sustainable future. In this thesis, kraft lignin is modified into methacrylated lignin (ML), lignin grafted with methacrylate functionalities at its hydroxyl sites. ML was incorporated at loading percentages of 10-31 wt.% into UV-cured coatings and the developed coatings were characterized according to their different properties. The methacrylation process was optimized via response surface methodology using a central composite design to determine the effect of different reaction variables on the process’ recovered mass yield and to obtain the maximum possible recovered ML. The ML obtained from the optimized reaction conditions was then incorporated at 30 wt.% into a siloxane-based UV-cured coating as a proof of concept for the practicality of the optimization process. ML was afterwards converted into a primary polyphosphine (lignophine) by a phosphane-ene reaction. The primary lignophine was then capped into tertiary alkylated and fluorinated lignophines, respectively using corresponding alkenes. The ability of the tertiary alkylated lignophine to coordinate to transition metals and sequester transition metal containing catalysts was determined using silver triflate a ring closing metathesis (RCM) reaction using Grubbs I (GI) catalyst, respectively. Finally, the tertiary alkylated lignophine was converted into a free-standing UV-cured polyphosphonium (lignophonium) network. The obtained films showed high cure percentages and water contact angles, along with a surface charge density value well over the necessary threshold for antimicrobial films and swelling degrees suitable for controlled drug release. The films were probed for their controlled drug release ability using diclofenac as the loaded drug and examining the release in PBS and showed a promising release profile.

▼ This dissertation presents novel biodegradable and photo-crosslinkable poly(-caprolactone) acrylates (PCLAs) to achieve polymer networks with controllable surface chemistry, stiffness, and topographical features, as well as crystallization-induced PCL, poly(3-hydroxybutyrate) (PHB) and poly(L-lactic acid) (PLLA) surfaces for investigating cell-material interactions. Chapter I reviews the recent progress of injectable polymeric biomaterials in the last decade for various tissue engineering applications. Chapter II investigates the variation of thermal and mechanical properties of PCL triacrylate (PCLTA) networks with different crosslinking time, and further studies the smooth muscle cell (SMC) responses to these networks. Chapter III studies the SMC responses to hydrolyzed PCLTA/methoxyl polyethylene glycol monoacrylate (mPEGA) networks, and the in vitro degradation of the crosslinked PCLTA and PCLTA/mPEGA networks. Chapter IV introduces the synthesis, and characterization of four-arm and six-arm PCLAs, and further demonstrates SMC responses to tunable stiffness of the photo-crosslinked PCLA networks. Chapter V investigates the roles of microgroove dimensions in promoting SMC functions on photo-crosslinked PCLA substrates, and further reveals SMC migration can be altered by microgroove dimensions. Chapter VI presents a facile method to synthesize photo-crosslinkable polyhedral oligomeric silsesquioxane (POSS)-PCL diacrylate (POSS-PCLDA) elastomers using POSS as initiator for potential applications in cardiovascular and peripheral nerve regeneration. The crystallinity of PCL network was compressed by POSS molecule, and the amorphous POSSPCLDA networks were elastomeric at physiological temperature. Chapter VII describes the epitaxial crystallization and surface segregation in modulating pre-osteoblastic cell behavior on PCL/PEG substrates. PCL/PEG films had different morphologies on different substrates, and introduced different cell behaviors. Chapter VIII investigates the SMC responses to PHB spherulites. Instead of the banded structures, the cracks on the PHB films were found to be more important in regulating cell alignment. Chapter IX presents the role of PLLA crystallization in regulation cell behaviors. Rougher surfaces of PLLA were found to be worse in supporting cell attachment and proliferation.

▼ Various techniques of fabricating surface patterns of small scales have been widely studied due to the potential applications of surface patterns in a variety of areas. It is a challenge to fabricate well-ordered surface area efficiently and economically. Evaporation-induced surface patterning is a promising approach to fabricate well-ordered surface patterns over a large area at low cost. In this study, the evaporation-induced surface patterns with controllable geometrical characteristics have been constructed. The dewetting kinetics on deformable substrate is also investigated. Using simple templates to control the geometry and the evaporation behavior of a droplet of volatile solvent, various gradient surface patterns, such as concentric rings, multiple straight stripes formed with a straight copper wire, etc. have been constructed on PMMA films. The wavelength and amplitude are found to decreases with the decrease of the distance to the objects used in templates. There is also a nearly linear relation between the amplitude and wavelength. The effects of several experimental parameters on the geometrical characteristics of the surface structures are studied, i.e. dimensions of the template, film thickness (solution concentration), substrate temperature, etc. The wavelength and amplitude increase with the increase of the film thickness (solution concentration), with the increase of the dimension of the template. However with the increase of the substrate temperature, the wavelength increases, while the amplitude decrease. Hexagonal network in pre-cast PMMA film have been fabricated by a “breath figure” approach at low humidity and low substrate temperature. The dimensions of the hexagonal holes are dependent on the template size and film thickness. The kinetics of the evaporative dewetting of a liquid (toluene) film on a deformable substrate (PMMA film) with the confinement of a circular copper ring is also studied. The liquid film first dewets from the outside towards the copper ring. When a critical volume is reached, an internal contact line appears, which dewets from the center to the copper ring smoothly with a constant velocity, then switches to a “stick-slip” motion. The average velocity of the smooth motion increases with the increase of the copper ring size and film thickness.

▼ Diels-Alder chemistry was utilized to manipulate the surface energy of glass substrates in reversible manner. Glass slides and capillaries were functionalized with hydrophobic dieneophiles resulting in a non-wetting surface. A retro Diels-Alder reaction facilitated by the thermal treatment of the surface’s function to cleave the hydrophobic dieneophile and resulted in the fabrication of a hydrophilic surface. Contact angle (CA) measurements were used as preliminary measurements for monitoring the changes in surface energy exhibited during the initial hydrophobic state (CA - 70±3°), after attachment of the dieneophile creating a hydrophobic state (CA - 101±9°) followed by reestablishment of the hydrophilic state (CA - 70±6°) upon cleavage of the Diels-Alder adduct. The treatments developed on flat glass surfaces were transferred to glass capillaries, with effective treatment confirmed by fluid column measurements. Effective flow gating was developed in the capillaries via patterning of the surface with hydrophilic/hydrophobic regions. Finally, attempts to create self-pressurizing capillaries were unsuccessful due to pronounced contact angle hysteresis for the hydrophobic surface treatment. Indium-tin oxide (ITO) substrates were functionalized with successive surface intiated atom transfer radical polymerization (SI-ATRP) and electropolymerization. A novel hybrid styrenic/thiophene monomer (ProDOT-Sty) was synthesized and employed in the polymerization events. This unique monomer and combination of polymerization methods allowed for the templation of electropolymerized poly(3,4-alkyleneoxythiophene) brushes by first creating a poly(styrene) backbone via SI-ATRP. An ITO electrode functionalized with poly(ProDOT-Sty) brushes grafted from the ITO surface via SI-ATRP was analyzed via cyclic voltammetry which clearly indicated the electropolymerization event beginning at approximately +0.7 V vs Fc/Fc⁺_. Photo patterning of the phosphonic acid ATRP initiator immobilized on the ITO surface was undertaken in order to create a surface that would limit growth of the polymer species to a patterned area for facile film brush thickness characterization via atomic force microscopy (AFM) at a later time. This was accomplished via lithography with ultraviolet radiation (UV) and was confirmed via scanning electron microscopy (SEM). A nanohetero structure composed of platinum tipped cadmium selenide seeded, cadium sulfide nanorods ([email protected] NRs). CdSe quantum dots (QDs) with variable sizes were prepared by adjusting reaction temperatures and times. CdS nanorods were then grown utilizing the CdSe QDs as seeds. Various lengths of the [email protected] NRs were produced that ranged from ~25 nm to ~135 nm. Investigation of the influence of the various synthetic conditions of the nanorod synthesis led to the conclusion that the ratio of CdSe seeds to Cd and S precursors could be manipulated in order to influence the length to which the nanorods grew. Pt tips were attached to an end of the… Advisors/Committee Members: Dr. Philip J. Costanzo.

▼ The focus of this research was the application of organic synthesis for new monomer development of Reversible Addition Chain Transfer (RAFT) compounds (i.e. trithiocarbonates and allyl sulphides), and the application of these monomers into photostimuli responsive networks designated as Covalent Adaptable Netowrks (CAN's). A mild, efficient, and high yield synthesis of a variety of trithiocarbonates and allyl sulphide containing AFCT (Addition-Fragmentation Chain-Transfer Termination) monomers containing terminal (meth)acrylate functional groups was presented. The ability of these monomers to control the mechanical and polymerization properties of thiol-Michael and chain-growth polymer networks in a previously unattainable manner is described. Controllable Reversible Addition-Fragmentation Termination (CRAFT) compounds structure-property relationships related to the RAFT compositional structure as it impacts photoplasticity and in-situ polymerization volumetric shrinkage stress in CAN's was investigated. Synthesizing, evaluating, and systematically varying CRAFT monomers expanded the range and functional capabilities of addition-fragmentation capable network forming monomers. Subsequent assessment of the impact of these monomers on photoplasticity and volumetric stress reduction was performed. With the detailed understanding of the structure-property relationships of the CRAFT monomers, these monomers were employed in networks for new applications in the field of stimuli responsive networks. The bond reshuffling and bond exchange reactions observed in CAN's were expanded to internetwork reshuffling for the development of on-demand adhesives. The application of polymer networks containing RAFT moieties that promote bond exchange only upon photoinitiation was demonstrated. By incorporation and variation of the RAFT chemical structure a versatile and wide-ranging methodology for adhesion was developed. Finally, the design of a new RAFT alkyne was employed into thiol-yne networks, and the ability to reduce polymerization induced shrinkage stress in thiol-yne and hybrid thiol-yne systems was demonstrated. A novel mechanism of bond rearrangement by aryl alkynes was discovered. The combination of the yne and AFCT mechanisms permitted the formation of highly crosslinked thermosets exhibiting high refractive indices with minimal volumetric shrinkage stress. In particular, the application of chain transfer motifs into CANs for advances in polymeric materials. Advisors/Committee Members: Christopher N.

▼ Stimuli-responsive polymeric materials have been now widely researched toward the biomedical applications including therapeutic delivery, bio-sensor surface modification, and tissue-engineering, etc., considering their desirable biocompatibility, tunable properties, and sensitivity toward physiological stimuli. Beyond the monoresponsive materials, polymers with responsiveness simultaneously toward multiple stimuli are paid great attention to because the control of responsive behaviors could be achieved at a more accurately and delicately level in a complex local environment. However, many challenges still exist such as maintaining integrity of the structure, shaping the morphology at micro- and macro-scale, and regulating a controllable and predictable transition behavior. The objectives of this dissertation are to develop and optimize multi-responsive polymeric materials toward the physiological stimuli including temperature, pH, and oxidative stress, in the forms of nano-/micro-scaled particles, nano-scaled multilayers, and macro-porous scaffolds. Specifically, micro/nano-scale polyetheramine containing hydrogel particles with pH-, thermo-, and oxidation-responsiveness were developed via thermally induced phase separation for therapeutic delivery (Chapter 2). The physical properties, including size, surface charge density, swelling behaviors are tunable via varying the preparation parameters such as monomer ratio, reaction time and temperature, monomer concentration, and monomer composition. Cytocompatibility and drug loading capability were investigated, and proved these particles to be of great potential for biomedical applications. For construction of dual-responsive multilayers, pH sensitivity was incorporated into a thermo-responsive polymer (poly(N-vinyl-2-caprolactam)) (PVCL) via bearing a tert-butoxycarbonylmethyl group at the 3-position of VCL through the approach of nucleophilic substitution (Chapter 3). The biocompatibility exhibited in acute cytotoxicity assay and the successful layer-by-layer self-assembly with a cationic polymer suggested a possible application for bio-sensor surface modification. Macro-porous hydrogels with pH-, thermo-, and oxidation-responsiveness were successfully fabricated via thermally-induced phase separation of prepolymers toward the application as scaffolds for neuronal regeneration (Chapter 4). The hydrogels exhibited micro-sized interconnected cavity for diffusion of nutrition and metabolites, hydrophobic domains for therapeutic delivery, great biocompatibility in direct contact assay, and cationic functional groups for survival of neuronal cells as well as neurite outgrowth, indicating a probable use for neuronal regeneration.

▼ Acid- and ion-containing polymers have interchain interactions that alter polymer behavior at the nano, micro, and bulk length scales. Strong secondary-bonds act as thermo-reversible physical crosslinks between chains which drive self-assembly. Tuning theses interactions can modify bulk polymer properties including stiffness, toughness, melt viscosity, resilience, clarity, abrasion resistance and puncture resistance. Furthermore, understanding and improving the relevant factors that control transport properties would have vast implications on developing solid polymer electrolytes (SPEs) for technologically important applications including water desalination, ion exchange membranes and microelectronics. This thesis explores the structure – processing – morphology - property relationships of acid and ionic functionalized polymers. Improvements in synthetic techniques and advancements in characterization methods have enabled new studies of associating polymer systems. Synthesis of entangled, high molecular weight, linear polyethylene (PE) chains functionalized with interacting pendant groups (acidic or ionic) placed periodically along the polymer backbone represent a new class of associating polymers. These polymers with periodic distributions of acid groups are much more homogenous than the commercially available polymers. Previous studies of these polymers with greater structural homogeneity revealed great variety in morphologies of the nano-aggregated polar groups within the non-polar polymer matrix. This thesis correlated the morphologies with bulk properties through real-time X-ray scattering and tensile deformation at a range of temperatures and sample compositions. New, transient morphologies and hierarchical morphologies were observed which coincided with unusual tensile strain hardening. These results indicate that improvements in synthetic control of polymers can enhance physical properties such as tensile strain-hardening, through cooperative bonding between chains. The structural regularity of precise polyethylenes also enables robust comparisons between experiments and computer simulations. At pico- to nano-seconds time scales and length scales of polymer and aggregate dynamics, neutron scattering and molecular dynamics simulations were combined to extend the knowledge of the molecular-level aggregated polymer dynamics. These experiments provide a baseline for future studies of ion-conduction in associating polymer melts.
