▼ This research includes two topics. The first topic is prepared a series of poly(methyl methacrylate) (PMMA)-based copolymers through free radical copolymerizations of methyl methacrylate in the presence of the either 2 - vinyl - 4,6 -diamino - 1, 3, 5triazine(VDAT) or vinylbenzyl -thymine (VBT). Using 1H nuclear magnetic resonance (NMR) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), we investigated the thermal properties and hydrogen-bonding interactions within blends of the two copolymers poly(2-vinyl-4,6-diamino-1,3,5-triazine-co-methyl methacrylate) (PVD AT-co-PMMA) and poly(vinylbenzylthymine-co-methyl methacrylate) (PVBT-co-PMMA). A large positive deviation in the behavior of the glass transition temperature determined by using the Kwei equation and DSC analyses indicated that strong multiple hydrogen-bonding interactions existed between the two copolymers. The FTIR and solid-state NMR spectroscopic analyses provided positive evidence for the presence of three hydrogen bonds between the diamino-1,3,5-triazine groups of PVDAT and thymine groups of PVBT. The second topic is synthesized a series of alkyne end-terminated poly(Î³-Benzyl L-glutamate) (alkyne-PBLG), which was prepared by the ring-opening polymerization of the N-carboxyanhydride monomer of Î³-Benzyl L-glutamate-carboxyanhydride. Then combination of the alkyne-PBLG with polyhedral oligomeric silsesquioxanes (POSS) with eight function groups are prepared through the click reation and formed a peptide-based block polymer with Î±-helice and Î²-sheet conformations. The thermal properties and structure of these polypeptides were characterized by using 1H NMR and FTIR. The FTIR, solid-state NMR and WXRD spectroscopic analyses provided evidence for the change of secondary structure between POSS and terminated peptide group, so that the conformation of Î²-sheets and Î±-helices would be influenced by the incorporation of POSS nanoparticle.

▼ Polymeric particles formed on a nanometric scale are of fundamental interest today, especially when used as carrier systems in the controlled release of drugs, cosmetics and nutraceuticals, as well as in the coating of materials with magnetic properties. The present study aims to develop a system for the production of poly (methyl methacrylate) (PMMA) and polycaprolactone (PCL) particles from the atomization of polymer solution in antisolvent medium. In this system, polymer solutions in different solvents are prepared and atomized in the form of a spray. The droplets generated with the atomization come into contact with an antisolvent liquid which causes the precipitation and formation of the polymer particles. In this work, experiments using the proposed system were performed under different operating conditions and the particles obtained were analyzed by Dynamic Light Scattering (DLS), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The results demonstrated that it is possible to obtain particles with characteristics of nanospheres / nanocapsules and nanofibers with size distribution in the range of 50 to 5000 nm. It was also possible to observe that the process variables such as the nature of the polymer, type of solvent (acetone, ethyl acetate, ethyl alcohol, isopropyl alcohol and propyl alcohol), atomization pressure (0.25-3 bar) and antisolvent medium temperature (10-40°C) directly affect the morphology and particle size distribution (DTP). In addition, the potential of encapsulation of the proposed system was evaluated. Cotton oil and iron aluminate (inverse spinel) were used as the material to be encapsulated. The particles produced in this evaluation were analyzed by DLS, MET, field emission scanning electron microscopy (MEV-FEG), Fourier Transform Infrared Spectroscopy (FTIR) and X-ray diffraction (XRD) for the encapsulation check. According to these results, it was verified the formation of carrier particles, with characteristics of nanocapsules and nanospheres. That is, the encapsulated material can be found within the polymer particle or adhered to the surface thereof, respectively.

▼ Carbon nanotubes (CNTs) exhibit high electrical and thermal conductivity and good mechanical properties, making them suitable fillers for composites. Their effectiveness as a filler is affected by their state of aggregation. Various solvents, surfactants, and processing techniques have been studied to improve CNT dispersion in polymers. However, prior to this work there is no suitable solution for achieving good CNT dispersion. In this study, a novel process has been developed that prevents CNT aggregation. Ordered helical wrapping of poly (methyl methacrylate) (PMMA) has been achieved on single wall carbon nanotubes (SWNTs). PMMA wrapped SWNT dispersions in dimethylformamide (DMF) are found to be stable for over three months at room temperature. Ordered PMMA wrapping has been confirmed by X-ray diffraction, and the wrapping behavior has also been verified using molecular modeling. PMMA only wraps on SWNTs with diameter of ~1 nm and not on larger diameter CNTs, such as few wall and multi wall carbon nanotubes. PMMA wrapped SWNT dispersions have also been characterized using UV-vis and Raman spectroscopy which confirm exfoliation of PMMA wrapped SWNTs. The novel finding has been successfully leveraged for electrical energy storage and mechanical reinforcement. SWNT buckypapers, typically have a surface area of about 650 m2/g. Using PMMA wrapping, SWNT buckypapers with surface area as high as 950 m2/g have been processed. These buckypapers exhibited significantly higher energy storage performance when used as electrodes in electrochemical supercapacitor. At a given power density, the energy density of the high surface electrodes was more than four times higher than the best value reported in the literature to-date for carbon nanotube or graphene electrodes. Wrapping SWNTs with PMMA in buckypaper increased the modulus and tensile strength by a factor of 5.9 and 3.7, respectively, compared to pristine SWNT buckypaper. Stress transfer studies on buckypapers revealed that while non-wrapped SWNTs experienced negligible stress during deformation, PMMA wrapped SWNTs took up to ~1 GPa stress before mechanical failure of the buckypaper. The modulus of composite films with PMMA wrapped SWNTs was 75 % higher than non-wrapped SWNT films. The effect of PMMA wrapping on thermomechanical properties and electrical conductivity of composite films is also reported. PMMA wrapped and non-wrapped SWNTs were incorporated in PAN fibers and the effect of PMMA wrapping on mechanical properties, and stress transfer was characterized. The stress transfer analysis of SWNTs in precursor fiber indicated 45 % higher interfacial shear strength in PMMA wrapped SWNTs compared to non-wrapped SWNTs. PMMA wrapping effectively debundled SWNTs in the PAN fibers as evidenced by Raman spectroscopy of the precursor fiber. SEM images of the carbon fiber fracture surface revealed 60% reduction in fibril size when PMMA wrapped SWNTs were used instead of non-wrapped SWNTs.

▼ Les polylactides (PLA) sont une famille de polymères biodégradables et biocompatibles de la famille des polyesters aliphatiques. Lorsque le PLA est dans un milieu humide et à une température excédant le 60°C, il se dépolymérise rapidement par hydrolyse, étape préalable à la biodégradation du PLA. Le PLA est utilisé dans le domaine biomédical et dans la fabrication de nombreux produits destinés, entre autres, à l’usage alimentaire tels que des emballages, des ustensiles et de la vaisselle jetable. Cependant, quand des applications à longue durée de vie sont visées, sa dégradation peut devenir une propriété non désirable. À cet égard, le mélanger avec un autre polymère est une des alternatives les plus simples et peu coûteuses afin de limiter cette dégradation. Le polyméthacrylate de méthyle (PMMA), un polymère thermoplastique et biocompatible avec de bonnes propriétés mécaniques et thermiques, est un candidat potentiel. Ce travail de recherche, divisé en deux étapes, consiste en l’étude de l’hydrolyse du PLA puis celle des mélanges PLA/PMMA aux températures supérieures à leur température de transition vitreuse, cela en milieu neutre, en milieu alcalin et, en certains cas, en milieu acide. La première étape de ce travail comprend l’étude de l’hydrolyse du PLA en fonction de sa capacité à cristalliser ainsi que de la température et de l’acidité du milieu d’hydrolyse en phase aqueuse. Pour l’effet de composition, deux PLA commerciaux qui différaient dans leurs ratios de compositions d’énantiomères L- et D- ont été sélectionnés. Le premier de ces PLA avait la capacité de cristalliser jusqu’à un taux d’environ 40% alors que le second était complètement amorphe. L’hydrolyse a été effectuée dans l’eau distillée (pH égal à 5.3) à 60, 70 et 80 °C pour évaluer l’effet de la température. Ensuite, les PLA ont été soumis à l’hydrolyse en milieu acide (pH égal à 1) et alcalin (pH égal à 12) à une température constante de 70°C afin d’évaluer l’effet de l’acidité et l’alcalinité du milieu. L’hydrolyse a été réalisée en suivant l’évolution de la perte de masse, du pourcentage d’eau absorbée, de l’évolution de la distribution de masse molaire et finalement de la température de fusion et du changement d’enthalpie qui y est associé. Les résultats ont montré que l’hydrolyse en milieu acide et neutre procède par un mécanisme d’érosion massique (i.e. érosion dans le cœur de l’échantillon) tandis qu’en milieu alcalin, l’hydrolyse du PLA suit principalement un mécanisme d’érosion surfacique. La cinétique de l’hydrolyse a été modélisée avec succès à l’aide d’un modèle exponentiel à deux étapes qui prend en compte chaque étape du mécanisme d’érosion. Indépendamment de leur composition énantiomérique et même si tous les échantillons étaient amorphes au début des essais, ils ont cristallisé rapidement durant l’hydrolyse. Dans une deuxième étape, l’hydrolyse des mélanges PLA/PMMA a été étudiée. L’ajout du PMMA avait pour but de ralentir la progression de l’hydrolyse puisque ce matériau est un polymère d’addition insensible à l’hydrolyse.

Le polyméthacrylate de méthyle (PMMA) est un thermoplastique présentant de nombreux avantages (transparence, légèreté, flexibilité). Cependant, le caractère inflammable du PMMA est un frein pour son utilisation dans de nombreuses applications, connaissant les pertes humaines et matérielles causés par les incendies. Cette thèse avait donc pour but d'améliorer la stabilité thermique et le comportement au feu du PMMA. Dans un premier temps, nous avons étudié l'influence de la dispersion de kaolins purs et traités sur le comportement au feu et la dégradation thermique du PMMA. Nous nous sommes ensuite orientés vers la modification chimique du PMMA par la méthode de copolymérisation du méthacrylate de méthyle (MMA) avec deux co-monomères phosphonés. Enfin, nous nous sommes intéressés à l'incorporation chimique ou physique de deux types de particules de polyhedral oligomeric silsesquioxane (POSS) dans le PMMA ou dans le PMMA modifié (copolymère (MMA – co- monomère monophosphoné)). Cette dernière partie a permis de mettre évidence l'effet bénéfique de la combinaison des particules de POSS et du PMMA modifié sur la dégradation thermique et l'inflammabilité de PMMA. Dans nos travaux, une attention particulière a été portée sur l'effet de phosphore en phase gazeuse et en phase condensée. Dans ce contexte nous avons pu définir, pour le PMMA modifié par les co-monomères phosphonés, un indice d'efficacité du phosphore pour chaque phase.

Poly(methylmethacrylate) (PMMA) is an important thermoplastic, widely used in industry. Unfortunately, it is a highly flammable polymer. The aim of this research was to improve the thermal stability and fire behavior of PMMA. First, we studied the influence of the dispersion of pure or treated kaolin on the fire behavior and thermal stability of PMMA. In second part of this work, the chemical modification of PMMA, using copolymerization of methyl methacrylate (MMA) with two phosphonated co-monomers was studied. Finally, we interested in chemical or physical incorporation of two types of polyhedral oligomeric silsesquioxane particles (POSS) in the PMMA or modified PMMA copolymère (MMA – co- monophosphonated monomer)). The effect of the combination of POSS particles and modified PMMA on the thermal degradation and flammability of PMMA was studied. In our work, the effect of phosphorus in the gas and condensed phase was separately studied. This study allowed us to define an efficiency index of phosphorus in each phase.

▼ The aim of this work was to study the rheological, mechanical and microstructural behavior of poly (methyl methacrylate)/polycarbonate (PMMA/PC) blends using a PMMA with elastomeric particles until phase inversion. The PMMA/PC blends were processed in single screw extruder and co-rotational twin screw extruder, with subsequent injection molding. The changes in the physical and chemical characteristics of the polycarbonate were analyzed by viscosimetry and by Fourier transform infrared spectroscopy (FTIR) before and after processing. The mechanical characterizations were performed by uniaxial tensile test and Izod impact. The rheological tests were done by melt flow index (MFI) and capillary rheometry. Microstructural analysis of the polymer blends was performed using atomic force microscopy (AFM) and scanning electron microscopy (SEM). The thermal degradation temperature was determined by thermogravimetric analysis (TGA). The results of the MFI in the processing conditions indicated a higher flowability of the polycarbonate among all the studied compositions; most of them present higher value of MFI for the materials processed in twin screw extruder. In the capillary rheometry of the unprocessed materials a lower PC viscosity variation was observed as a function of the shear rate increase. TGA showed a higher degradation onset temperature for the PC, but the processing altered the thermal stability of that polymer more than for poly (methyl methacrylate). The intrinsic viscosity measurements of the polycarbonate indicated a possible degradation by chain scission after processing due to the decrease in the molar mass of the material. The FTIR did not identify distinct bands for the PC before and after the processing. The mechanical characterization by uniaxial tensile revealed higher tensile strength, higher modulus of elasticity and greater elongation at break for polycarbonate, and the compatibility of PMMA/PC blends varied with PC concentration, with some compositions that showed synergism in the properties. Izod impact strength showed a high PC impact strength when compared to PMMA, but the addition of 20 wt% of PC in the PMMA matrix significantly increased the impact strength of PMMA/PC blends. The morphological analysis by AFM visualized the presence of spherical elastomeric particles with an average size of about 182 ± 20 nm in the PMMA, evenly distributed along its microstructure, while the PC presented only one homogeneous phase. The PMMA/PC blend showed two well-defined phases throughout all the compositions, and showed evidence of morphology with co-continuity characteristics for the compositions between 70/30 and 50/50 wt%, both for the materials processed in single screw extruders as well as twin screw extruders. The compositions with the highest percentage of PMMA in the PMMA/PC blends were the ones with the best results of rupture strength and elongation at break, and the Izod impact resistance showed intermediate properties. The results in the phase inversion followed the characteristics of the… Advisors/Committee Members: Ito, Edson Noriyuki (advisor), 40405036191 (advisor), http://lattes.cnpq.br/7249500407405478 (advisor).

Negli ultimi anni i copolimeri a blocchi hanno acquistato sempre maggiore interesse sia da un punto di vista accademico che industriale grazie alle loro potenziali applicazioni come membrane per la separazione di gas, come compatibilizzanti di miscele polimeriche e nel campo del nanopatterning. Il Bisfenolo A policarbonato (PC) ed il polimetilmetacrilato (PMMA) rappresentano importanti tecnopolimeri e trovano impiego in svariati campi di applicazione quali: ottico, automobilistico, elettronico, arredamento e costruzioni per questo motivo risulta auspicabile l'ottenimento di copolimeri a blocchi PC/PMMA. E' stato sintetizzato il prepolimero (PC-2OH) terminato con gruppi bis-fenolici ad entrambi i lati della catena, il quale e' stato funzionalizzato mediante 2-bromoisobutiril bromuro e a-clorofenilacetil cloruro al fine di ottenere i macroiniziatori PCBr e PCCl. I macroinizatori sono stati poi utilizzati per la sintesi di copolimeri a blocchi PMMA-b-PC-b-PMMA mediante Polimerizzazione Radicalica Vivente. Sono stati sintetizzati tre copolimeri a rapporti molari PC/MMA diversi: (1:1000), (1:500), (1:100). Il prepolimero, i macroiniziatori, ed i copolimeri ottenuti sono stati caratterizzati mediante NMR,SEC, DSC, TGA e MALDI-TOF, AFM e SEM. I risultati prodotti da questo lavoro di ricerca hanno permesso di ottimizzare i parametri di reazione sia per la sintesi del PC-2OH che dei macroiniziatori e di sintetizzare e caratterizzare copolimeri di e triblocco mediante ATRP in merito ai quali ad oggi non sono presenti molti riferimenti bibliografici.

During the last decades block copolymers have gained more interest from both academic and industrial point of view because of their potential applications as membranes for gas separation, as compatibilizers in polymer blends and for nano-patterning. Bisphenol A polycarbonate (PC) and polymethylmethacrylate (PMMA) are important engineering plastics used in several applications such as optical, automotive, electronics, furniture and construction. Considering their properties it is advantageous to obtain block copolymers of PC/PMMA. It was synthesized prepolymer (PC-2OH) terminated with bis-phenol groups at both ends of the chain, which has been functionalized by 2-bromoisobutiril bromide and a-clorofenilacetil chloride in order to obtain the macroiniziators PCBr and PCCl. These macroinizators were then used for the synthesis of block copolymers PMMA-b-PC-b-PMMA by Living Radical Polymerization (ATRP). Three copolymers were synthesized in different (1:1000) (1:500) (1:100) molar ratios of PC/MMA. The prepolymer, the macroiniziators, and the copolymers obtained were characterized by NMR, SEC, DSC, TGA,MALDI-TOF, AFM and SEM. The results of this research have allowed us to optimize the reaction parameters for both the synthesis of PC-2OH and the macroiniziators and to synthesize and characterize di- and tri-block copolymers.

A principal motivação para a realização deste trabalho de mestrado consistiu na idéia de que a obtenção de nanoblendas poliméricas é fundamentalmente dependente da elevada interação entre as fases presentes na mistura. A estratégia adotada neste estudo baseou-se na utilização de dois polímeros que possuem uma janela de miscibilidade, o que permite o estabelecimento de uma condição de imiscibilidade muito próxima do limite desta janela, proporcionando reduzida tensão interfacial entre as fases. Nanoblendas poliméricas a base do poli(metacrilato de metila) (PMMA) como matriz e do copolímero poli(estireno-co-acrilonitrila) (SAN) como a fase nanométrica foram obtidas através da mistura mecânica em uma extrusora dupla rosca de bancada. A compatibilização entre as fases foi realizada através da incorporação do terpolímero (MGE) sintetizado a partir dos monômeros metacrilato de metila (MMA), metacrilato de glicidila (GMA) e acrilato de etila (EA). A morfologia das blendas foi caracterizada por microscopia eletrônica de transmissão (MET). A transparência das blendas bem como dos polímeros puros foi quantificada através de um ensaio de transmitância de luz visível. Também foram realizados ensaios de reometria de torque, reometria capilar, resistência à tração e resistência química a solventes. Na ausência do agente MGE foram obtidas nanoblendas para 1 e 3% em massa da fase dispersa. A introdução do terpolímero permitiu uma significativa redução no diâmetro numérico médio da fase SAN para as composições com 5 e 10% em massa. Essa diminuição fez com que fase dispersa da blenda com 5% de SAN atingisse dimensão inferior a 100 nm. Foi verificado que a transparência das blendas está diretamente relacionada à fração mássica da fase dispersa. As propriedades mecânicas das blendas foram próximas as da matriz. Os polímeros puros e as blendas não sofreram inchamento pelos solventes escolhidos.

The motivation for this work was the idea that nanoblends are fundamentally dependent on the high interaction between the phases in the mixture. The strategy adopted in this study was based on the use of two polymers that have a miscibility window, which allows the establishment of an immiscibility condition very close to the limit of this window, providing low interfacial tension between phases. Nanoblends of poly(methyl methacrylate) (PMMA) as the matrix and poly(styrene-co-acrylonitrile) (SAN) as the nanophase were obtained by blending in a twin screw extruder. The compatibilization between the phases was accomplished through the incorporation of the terpolymer (MGE) synthesized from the monomers methyl methacrylate (MMA), glycidyl methacrylate (GMA) and ethyl acrylate (EA). The morphology of the blends was characterized by transmission electron microscopy (TEM). The transparency of the blends and pure polymers was quantified by transmittance of visible light. Tests such as torque rheometry, capillary rheometry, tensile strength and chemical resistance to solvents were also performed. Nanoblends with 1 and 3 wt% of the dispersed phase were…

▼ A model of the initial complement mediated inflammatory response to tissue engineering (TE) scaffolds is developed in this study. TE has been given increasing attention in cases of large defects caused by severe trauma or disease based on the concept that the scaffold degrades and is replaced by tissue regeneration. Numerous attempts have been made to modify biomaterials chemical compositions, mechanical properties, and biomolecular incorporation to improve biocompatibility. The surface properties have been shown to affect host inflammatory responses and the ultimate fibrous capsule formation through foreign body reaction around implanted biomaterials. Although extensive research has been conducted regarding immune responses, such as macrophage activity, upon biomaterial particles and to a lesser extent on biomaterials surface, the inflammatory cascade and its effect on differentiation of preosteoblasts is not completely understood. Biomaterials are known to adsorb serum proteins and activate the complement system followed by subsequent inflammatory cascade. Complement activation through either direct deposition or interaction with adsorbed protein layer on biomaterial surface is believed to be the initiation process of inflammatory responses to implanted biomaterials. By setting the goal of constructing a tissue engineering model, the present study utilizes complement, macrophages, and preosteoblast-like cells to investigate the initial step of the inflammatory response and their effect on osteogenesis on biomaterial surface, poly(methylmethacrylate). PMMA polymer with different tacticities effects on MC3T3-E1 cell proliferation and differentiation were evaluated with cell proliferation and viability assay (MTS assay). In addition, their effect on MC3T3-E1 cell differentiation was assessed with MTS assay and osteogenic activity markers quantifications. No significant differences between different tacticity PMMA and tissue culture polystyrene were found. The effect of complement on macrophage, RAW264.7, activation on biomaterial surface was investigated in present study. Three cytokines, TNF-a, IL-6, and IL-1ß, expression were quantified with ELISA to evaluate macrophage activation on PMMA surfaces and particles. Cytokine expressions on PMMA surface were not significantly different from control group. At 6 hour, 1-10 µm PMMA beads induced significantly increased TNF-a expression. Mouse complement pretreatment resulted in increased expression of IL-6 and decreased expression of TNF-a while IL-1ß was barely detectable in present experimental conditions. Co-culture system is constructed by means of transferring RAW264.7 cell culture media to preosteoblast culture with corresponding material surfaces or particulates. The mRNA expression of Runx2, ON, and Collagen Type I are quantified with real time PCR to evaluate osteogenic activity of MC3T3-E1 cells under osteogenic condition. MC3T3-E1 cells cultured with osteogenic media supplemented with RAW264.7 cell culture media with LPS showed elongated… Advisors/Committee Members: Schricker, Scott (Committee Chair).

▼ Os polímeros PMMA e PVC fabricados no Brasil são utilizados na confecção de artefatos médico-farmacêutico esterilizáveis por radiação ionizante. Contudo, quando esses polímeros são expostos à radiação gama, podem sofrer alterações na sua cadeia principal. Tais alterações acarretam em degradação molecular e conseqüente mudanças nas suas propriedades físicas. Portanto, a estabilização radiolítica do PMMA e do PVC torna-se fundamental para viabilização desses polímeros na fabricação de artefatos radioesterilizáveis. Neste estudo foram testados dois estabilizantes, um aditivo comercial tipo HAS (Hindered Amine Stabilizer) originalmente utilizado na estabilização foto-oxidativa de polímeros e uma mistura de sais inorgânicos (CuCl2/KI) estudada previamente na estabilização termo-oxidativa de sistemas poliméricos. Os resultados encontrados para os sistemas com PMMA mostraram que o HAS incorporado ao sistema na concentração de 0,3% (m/m) confere uma radioproteção de 61%. Este resultado significa uma redução do valor G (cisões/100eV) de 1,23 para 0,48 no intervalo de 0 a 100kGy. Ensaios térmicos mostraram que o HAS na concentração de 0,3% (m/m) também contribui para a estabilização térmica do PMMA. Por outro lado, nenhuma concentração da mistura de sais mostrou-se eficiente na estabilização radiolítica do PMMA. Para os sistemas baseados no PVC, o HAS não apresentou nenhuma ação estabilizante, provavelmente pela ação do HCl liberado na radiólise da matriz polimérica. O sistema com a mistura de sais apresentou o mesmo comportamento de degradação radiolítica do que o sistema controle, contudo a mistura de sais na concentração de 0,5% (m/m) conferiu uma melhora nas propriedades térmicas do PVC, aumentando em 44°C a temperatura de máxima degradação térmica (liberação de HCl) do polímero. Os ensaios mecânicos realizados para os sistemas de PMMA e PVC indicaram que a mistura de sais foi o estabilizante que mais influenciou nas propriedades mecânicas dos polímeros, com destaque na propriedade módulo de elasticidade que para o PVC aumentou em 23% quando comparado com o PVC-controle. Por outro lado, o PMMA-sais tem seu módulo de elasticidade aumentado em 36% em relação ao PMMA-controle. As análises espectroscópicas na região do infravermelho (FT-IR) mostraram que a presença dos estabilizantes (HAS e CuCl2/KI) nos sistemas de PMMA e PVC não modificaram suas estruturas Advisors/Committee Members: ARAÚJO, Elmo Silvano de (advisor).

O transistor orgânico de efeito de campo com arquitetura vertical (VOFET) possibilita contornar as principais limitações de um transistor orgânico de efeito de campo (OFET) convencional. Nesta estrutura, as camadas são empilhadas verticalmente, de modo que os eletrodos de fonte e dreno são separados pela camada semicondutora e o comprimento do canal definido pela espessura do filme semicondutor. Para o VOFET proposto, utilizou-se Al e Al2O3 (obtido por anodização) como eletrodo e dielétrico de gate, respectivamente. O filme semicondutor foi obtido pela deposição por spincoating de P3HT dissolvido em clorofórmio. Os eletrodos de fonte e dreno foram obtidos por evaporação térmica a vácuo. Ao utilizar Al e Au como fonte e dreno, respectivamente, foi possível estudar os dispositivos de dois terminais que compõe o VOFET. Com base nesses dispositivos, importantes parâmetros da estrutura vertical foram determinados, como capacitância do dielétrico (~265 nF/cm2), densidade de portadores e mobilidade do P3HT (NA = 9,2 x 1016 cm-3 e μ = 1,5x10-4 cm2V-1s-1). Para utilizar Sn como eletrodo de fonte, o filme foi avaliado por meio de medidas de resistência e capacitância, aliadas à analise morfológica por AFM. Observa-se que a adição de uma camada de PMMA sobre o Al2O3 melhora o desempenho do VOFET. Para o VOFET formado por Al2O3/PMMA (20 nm/14 nm), com Sn e Al como fonte e dreno, foram calculados os valores de densidade de corrente (Jeff = 7x10-3 mA/cm2), voltagem e campo limiar (VTH = -8V e ELIMIAR = 330 MV/m). Com isso, foi obtido um VOFET utilizando filme de Sn evaporado como eletrodo de fonte perfurado.

A way of circumvent the limitations of conventional organic field-effect transistor (OFET), is by using the vertical organic field-effect transistor (VOFET). In this structure, with layers stacked vertically, the semiconductor is sandwiched between source and drain electrodes, where the channel length is determined by the thickness of the semiconductor film. In this study, we report a VOFET with Al and Al2O3 (obtained by anodization) as electrode and dielectric of gate, respectively. The semiconductor film was obtained by spin-coating of the P3HT in chloroform. We obtained the source and drain electrodes by vacuum thermal evaporation. The use of Al and Au as source and drain, respectively, enabled the investigation of the two devices contained in the VOFET (MIM capacitor, Schottky diode and MIS capacitor). Important parameters were determinate, as dielectric capacitance (~265 nF/cm2), charrier density and mobility of P3HT (NA = 9,2 x 1016 cm-3 e μ = 1,5x10-4 cm2V-1s-1), etc. To use Sn as source electrode, the film (by evaporation) was investigated by measurements of resistance and capacitance, combined with morphological analysis by AFM. We observed that the addiction of PMMA layer on Al2O3 improves the performance of VOFET. For VOFET obtained by using Al2O3/PMMA (20 nm/14 nm) as dielectric layer, with Sn and Al as source and drain, respectively, were calculate the values of current density (Jeff = 7x10-3 mA/cm2),…

▼ Copolímeros, macromoléculas orgânicas ou inorgânicas com alta massa molar, consistem de unidades monômericas repetidas, unidas por ligações covalentes e que apresentam mais de um tipo de monômero. Neste trabalho estudamos três copolímeros constituídos por dois blocos distintos, isto é copolímeros dibloco, onde um dos blocos é constituído pelo polimetacrilato de metila, PMMA e o outro pelo polimetacrilato de N,N dimetilamino, PDMAEMA, e o homopolímero de PDMAEMA. A fórmula geral dos copolímeros dibloco estudados é PMMAm-b-PDMAEMAn onde o número de monômeros de cada bloco é representado pelos índices m e n. Os copolímeros PMMA1-b-PDMAEMA6,3 (MM, 54.200), PMMA1-b-PDMAEMA3,0 (MM 27.558), o PMMA1-b-PDMAEMA1,1 (MM 25.555) e o homopolímero PDMAEMA (MM 41.614,9) tiveram suas massas molares e a razão entre os monômeros de cada bloco caracterizados por cromatografia de gel permeação, GPC, e NMR. Determinamos a concentração micelar crítica (CMC) dos copolímeros e verificamos, por RMN e fluorescência, o efeito da concentração e do pH na sua agregação. A interação dos copolímeros com vesículas unilamelares grandes, LUVs, preparadas com misturas de fosfatidilcolina, PC, e fosfatidilglicerol, PG, foi estudada em diferentes condições de pH e força iônica. A interação dos polímeros com as LUVs também foi estudada medindo-se o diâmetro hidrodinâmico e potencial zeta das LUVs na presença dos polímeros. Observou-se que, quando a razão polímero/lipídio é alta, os polímeros se ligam às LUVs, neutralizando completamente a carga das vesículas. Quando a concentração de LUVs é próxima à dos polímeros, forma-se uma rede que conduz à agregação e precipitação dos complexos. Estudamos o efeito dos polímeros na permeabilização de LUVs e vesículas unilamelares gigantes (GUVs) preparadas com misturas de PC:PG. Os copolímeros permeabilizaram as LUVs, dependendo da razão polímero/lipídio, do pH, força iônica e das características hidrofóbicas e hidrofílicas de cada copolímero. Quanto maior a porcentagem de PG nas LUVs maior a interação com os copolímeros. A ligação dos copolímeros às LUVs deve produzir segregação dos fosfolipídios negativos na bicamada das LUVs (i.e., separação lateral de fases) facilitando a permeabilização das vesículas. Demonstramos que os copolímeros se ligam à superfície das GUVs modificando a sua forma e levando ao rompimento das vesículas. Estes efeitos foram modulados pelo pH e a força iônica do meio. O efeito de permeabilização dos copolímeros foi correlacionado com as razões entre os blocos hidrofóbicos e hidrofílicos. Quando o copolímero tem uma maior fração de PDMAEMA, o bloco mais hidrofílico do copolímero, este efeito é mais evidente. A porcentagem de permeabilização, após um tempo definido, para copolímeros de mesma massa molar, como o PMMA1-b-PDMAEMA3,0 (MM 27.558) e o PMMA1-b-PDMAEMA1,1 (MM 25.555), é muito maior com o copolímero com maior porção hidrofílica, o PMMA1-b-PDMAEMA3,0. O homopolímero DMAEMA também se mostrou eficiente na interação com as LUVs, porém menos que o PMMA1-b-PDMAEMA6,3.que possui maior numero de… Advisors/Committee Members: Cuccovia, Iolanda Midea, Florenzano, Fábio Herbst.
