Book excerpt: Nous étudions, par ellipsométrie spectroscopique, les propriétés optiques dans le domaine de l'UV-Visible-Infrarouge de films composites constitués de polymère et de nanoparticules d'or. Nous étudions la relation entre ces mesures et la structure des nanocomposites, que nous étudions par microscopie à force atomique en particulier. Nous distinguons l'analyse de films épais (tri-dimensionnels) et minces (quasi-bidimensionnels). Dans les deux cas, nous confrontons les résultats expérimentaux à des modèles théoriques de milieux effectifs dérivés de Maxwell-Garnett, en particulier.

Book excerpt: Ce travail de thèse a été consacré à l'étude expérimentale, théorique et numériquede métamatériaux auto-assemblés constitués de nanoparticules d'or, opérant dans la gammedu visible. Nous nous sommes intéressés à trois types de structures différentes et avons analyséleurs propriétés optiques par ellipsométrie spectroscopique.Nous avons étudié expérimentalement et numériquement l'effet de la proximité d'un substratde haut indice sur la réponse plasmonique d'une nanoparticule, grâce à un système expérimentalconstitué de monocouches de nanoparticules d'or sur une multicouche de polyélectrolytes.Nous avons discuté d'un effet d'exaltation de la section efficace d'absorption des nanoparticulesaux plus faibles distances au substrat. Nous avons montré que des films composites denses depolymère et de nanoparticules d'or ont des réponses contrôlées par la fraction en or et qu'ilsse comportent, à haute fraction en or, soit comme des diélectriques soit comme des métauxselon la gamme de fréquence. Nous avons développé un modèle phénoménologique, adapté àde nombreuses situations, qui décrit bien les propriétés optiques des films. Enfin, nous avonsétudié des nanocomposites lamellaires à base de copolymères à blocs et de nanoparticules d'or.Nous avons montré comment avoir accès, pour certains systèmes, à l'extraction et la modélisationde leur anisotropie de permittivité, qui est affectée par la résonance plasmonique desnanoparticules.

Book excerpt: Cette thèse porte principalement sur l'étude de certaines propriétés optiques de nanostructures d'oxyde de zinc (ZnO) sous forme de nanocristaux, de films minces, et en tant que composant nanométrique dans des composites à base de polymères conducteurs. La première partie du mémoire décrit la synthèse de ces matériaux qui a été effectuée à l'Institut des Matériaux Jean Rouxel, par différentes méthodes. Une étude poussée de la caractérisation morphologique et structurale est effectuée au moyen de la microscopie électronique et de la diffraction des rayons X, appuyée par quelques expériences de diffusion Raman. Dans le chapitre suivant, on découvre que ces nanomatériaux émettent une lumière intense dans l'ultraviolet et dans la région verte du spectre. La preuve du confinement quantique des excitons dans les particules de ZnO est apportée par les techniques d'aborption optique et de photoluminescence suivie par une description succincte des modèles régissant ce confinement. Vient ensuite l'analyse des propriétés émissives, notamment par spectroscopie résolue en temps. Les variations temporelles et spectrales de l'émission sont caractérisées en fonction de la taille et des défauts structurels des nanostructures. Le dernier chapitre aborde la synthèse et l'étude optique de matériaux composites obtenus en mélangeant des nanocristaux de ZnO avec des polymères conjugés tels que MEH-PPV, connus pour leurs propriétés de photoluminescence et leur application aux diodes électroluminescentes. Là encore des propriétés émissives remarquables en fonction de la taille des particules insérées sont mises en évidence.

Available in PDF, EPUB and Kindle. Book excerpt: Properties and fabrications of ultra-thin polymer films and hierarchical composites are of great interest in packaging, electronics, separations, and other manufacturing fields. However, due to the inherently fragile nature of ultra-thin polymer films, measuring their properties has proven difficult. Additionally, variables controlling thin polymer patterns (e.g. substrate wetting property) and composites (weight percent of particulates in matrix) formation have not been fundamentally well understood. Within this spectrum, fundamental understanding of formation mechanisms of these patterns and composites are needed. Additionally, a new characterization technique is required to be able to measure the mechanical properties of fabricated composites and thin films. The pattern (Chapter 2) and composite (Chapter 3) formation presented in this thesis is based upon flexible blade flow-coating, an evaporative self-assembly method. The impact of substrate wetting, varying from being hydrophobic (water advancing contact angle 113°) to hydrophilic (water advancing contact angle 27°), on polymer pattern formation is examined here (Chapter 2). We observe a variety of polystyrene structures including dots, hyper-branched patterns, stripes and lines that can be deposited on substrates with a range of wetting properties. We propose the mechanism for these pattern formations as a balance between Marangoni instability and solute absorption. When adding quantum dot nanoparticles into the polymer (poly(methyl methacrylate) solution in the flow-coating process on hydrophilic substrates, we could obtain free-standing hierarchical nanocomposite films with alternating line and film structures (Chapter 3). The ability to guide assemblies of nanoparticles and polymers in designated areas in one step via flow-coating, provides new understanding of the flow competition of mixing two components which are both on the nanometer scale. Additionally, we introduce a method designated for ultra-thin film tensile testing (Chapter 4). We demonstrate the capability of this method by stretching two-dimensionally macroscopic, yet nanoscopically thin, polymer films on the surface of water. Through laser tracking of the force and displacement on the film, we characterize the full stress-strain response of brittle (polystyrene), ductile (polycarbonate), and rubbery (cross-linked polydimethylsiloxane) polymer thin films. In the brittle (polystyrene) films, we observe a precipitous decrease in mechanical properties (Young's modulus, strain at failure, and nominal stress at failure) for film thicknesses approaching the size of an individual polymer chain (~ 25 nm) yielding insights into polymer chain entanglement theory. To verify our hypothesis in polymer chain entanglement theory for determining failure properties of thin polymer films, we further study the molecular weight effect (853, 490, 137 and 61.8 kg/mol) of polystyrene on failure properties (Chapter 5). We compare maximum tensile strain, maximum tensile stress, and modulus respectively as a function of molecular weight as well as film thickness. We support our hypothesis on polymer inter-chain entanglements theory in thin polymer films by this molecular weight study. This thesis provides direct measurements of failure properties of ultra-thin films. These findings have important implications for the design of materials used in wide range of applications, as well as for the pursuit of new fundamental understanding of polymer physics in confined states.

Book excerpt: Cette thèse porte sur l'étude de nanocomposites plasmoniques et, plus particulièrement, sur des couches minces de polymère dopées en nanoparticules d'or et d'argent. Les travaux réalisés concernent le développement de deux approches de fabrication originales fondées sur la synthèse in situ de nanoparticules dans une matrice de polymère sous irradiation. La première méthode envisagée étudie l'organisation de nanoparticules d'or dans les films de polymères en les irradiant de manière contrôlée dans l'espace par interférométrie laser. Ainsi, nous obtenons des réseaux de nanoparticules qui révèlent des propriétés de diffraction atypiques dont la réponse spectrale dépend fortement de la réponse plasmonique du système. Nous appelons ce phénomène diffraction amplifiée par plasmon. La seconde approche de fabrication développée a pour but de réaliser la synthèse de nanoparticules in situ dans des films de polymère sous rayonnement solaire concentré. Nous nous sommes intéressés, en particulier, à l'influence de l'irradiation solaire concentrée sur les processus de formation des nanoparticules et sur leur morphologie finale, dans le but de contrôler les propriétés optiques du système. Nous avons notamment montré qu'il est possible de contrôler la taille des nanoparticules d'or formées in situ dans les films de polymère, en faisant varier le flux du rayonnement solaire. En parallèle de ces travaux expérimentaux, une approche semi-analytique combinant une description des matériaux en termes de milieux effectif à la méthode RCWA (Rigorous Coupled Wave Analysis), a été développée pour calculer les propriétés optiques des nanocomposites.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, we develop new composite optical materials by the assembly of silica nanoparticles (NPs) into micron-scaled geometries and embedding them into selected polymer media to achieve tunable and synergistic optical properties for potential applications, including photovoltaics, photobioreactors, or solar-integrated smart windows. The size and the refractive index of NPs, and the geometric arrangements are explored to optimize the targeted optical properties, including forward scattering and the reflectance of light. We also explore different types of the polymer matrix to allow for matching refractive index or introducing stimuli-responsive light scattering. Firstly, we develop a novel design of semi-transparent composite films for delivering equal and optimally efficient "doses" of sunlight to photosynthetic cells, algae, in a photobioreactor system. The efficient re-distribution of solar flux can allow the algae to receive spatially diluted solar flux and thus avoid photodamages from the direct sunlight. We develop colloidal NPs are assembled into microspheres via water-based emulsion evaporation method which is easy to set up and suitable for large-scale fabrication. Backed by numerical calculations, the overall shape/size of the microsphere and the effective refractive index of the composites are optimized, the synthetic scatterers that recapitulate the salient forward-scattering behavior of the Tridacnid clam system are presented. These hierarchically structured beads also generate various structural colors due to the periodic packing of NPs, which allows back-reflection of photosynthetically inefficient green or yellow lights depending on the sizes of NPs. Our method is simple yet scalable, cost-effective, and environmentally benign, which inspires new designs for small-footprint biofuel applications. Secondly, we develop new strategies to tune the optical transmittance via mechano-responsive polymers. Stretchable smart window film consisting of an elastomer with micro-scale wrinkles and silica (SiO2) NPs can provide reversible and switchable transparency-opacity. We design and fabricate mechanically responsive films composed of silica NPs and elastomers. By incorporating deformable and controllable wrinkling patterns into the particle-embedded polymer systems with wrinkles and NPs on opposite side of the films, we achieve the desired transparency at a low mechanical strain (

Book excerpt: L'incorporation de particules inorganiques dans une matrice polymère confère de nouvelles propriétés au matériau ou améliore de manière significative les propriétés déjà existantes. Cependant, l'apparence visuelle perçue, telle que la transparence, peut être altérée par des phénomènes de diffusion de la lumière par les particules. Cette diffusion de la lumière est principalement conditionnée par la dimension des particules -ou agrégats de particules- et la différence d'indice de réfraction entre la matrice et les charges. Afin de traiter ces deux problèmes, l'objectif de nos travaux était de contrôler simultanément l'état de dispersion des nanoparticules inorganiques dans la matrice polymère et l'indice de réfraction des nanoparticules de façon à l'ajuster à celui de la matrice. Pour élaborer ce nouveau composite, nous avons synthétisé des nanoparticules hybrides cœur@écorce avec un cœur inorganique qui apporte les nouvelles propriétés et une écorce polymère d'épaisseur contrôlée, obtenue par polymérisation radicalaire contrôlée par voie nitroxyde amorcée à la surface des nanoparticules inorganiques. L'écorce polymère limite l'agrégation des particules et permet de modifier l'indice de réfraction moyen des nanoparticules cœur@écorce. En contrôlant l'épaisseur et la nature chimique de l'écorce polymère, nous cherchons à ajuster l'indice de réfraction des nanoparticules cœur@écorce à celui de la matrice. Les nanoparticules ont ensuite été dispersées dans une matrice de poly(méthacrylate de méthyle). Les propriétés optiques des composites ont été caractérisées par spectrogoniophotométrie, afin d'obtenir des informations sur l'intensité et la distribution angulaire de la lumière transmise par le composite. La transparence des nanocomposites a été fortement améliorée en ajustant l'indice de réfraction des nanoparticules cœur@écorce à celui de la matrice.

Available in PDF, EPUB and Kindle. Book excerpt: It is difficult to imagine how our highly evolved technological society would function, or how life would even exist on our planet, if polymers did not exist. The intensive study of polymeric systems, which has been under way for several decades, has recently yielded new insights into the properties of assemblies of these complex molecules and the physical principles that govern their behavior. These developments have included new concepts to describe aspects of the many body behavior in these systems, microscopic analyses that bring our understanding of these systems much closer to our understanding of simple liquids and solids, and the discovery of novel chemistry that these molecules can catalyze. This special topic volume of Advances in Chemical Physics surveys a number of these recent accomplishments. Supplemented with more than 250 illustrations, it provides a significant, up-to-date selection of papers by inter-nationally recognized researchers. Topics include: * Theory of Polyelectrolyte Solutions * Star Polymers: Experiment, Theory, and Simulation * Tethered Polymer Layers * Living Polymers * Transport and Kinetics in Electroactive Polymers Self-contained, authoritative, and timely, Polymeric Systems makes the cutting edge of polymer research available to scientists in every branch of chemical physics.

Available in PDF, EPUB and Kindle. Book excerpt: Glass Nanocomposites: Synthesis, Properties and Applications provides the latest information on a rapidly growing field of specialized materials, bringing light to new research findings that include a growing number of technologies and applications. With this growth, a new need for deep understanding of the synthesis methods, composite structure, processing and application of glass nanocomposites has emerged. In the book, world renowned experts in the field, Professors Karmakar, Rademann, and Stepanov, fill the knowledge gap, building a bridge between the areas of nanoscience, photonics, and glass technology. The book covers the fundamentals, synthesis, processing, material properties, structure property correlation, interpretation thereof, characterization, and a wide range of applications of glass nanocomposites in many different devices and branches of technology. Recent developments and future directions of all types of glass nanocomposites, such as metal-glasses (e.g., metal nanowire composites, nanoglass-mesoporous silica composites), semiconductor-glass and ceramic-glass nanocomposites, as well as oxide and non-oxide glasses, are also covered in great depth. Each chapter is logically structured in order to increase coherence, with each including question sets as exercises for a deeper understanding of the text. Provides comprehensive and up-to-date knowledge and literature review for both the oxide and non-oxide glass nanocomposites (i.e., practically all types of glass nanocomposites) Reviews a wide range of synthesis types, properties, characterization, and applications of diverse types of glass nanocomposites Presents future directions of glass nanocomposites for researchers and engineers, as well as question sets for use in university courses
