Download or read book New Developments in Polymer Composites Research written by Stephan Laske and published by Nova Science Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composite materials are made from at least two different materials with significantly different properties and behaviour. When such materials are combined, the produced composite has completely different characteristics compared to the individual components. In ancient Egypt, the earliest composite materials where created to form bricks out of mud and straw for building constructions. Polymeric composites are steadily growing and are one of the most promising material classes, which have the opportunity to deal with new challenges approaching from the market. These materials are often stronger, lighter or less expensive when compared to traditional materials, but the demands and needs are getting more diverse and complex. Modern composites comprise the incorporation of filler in micro and nanoscale, as well as the construction of specific structure especially the imitation of nature - to create new or improved material properties. This book gives an overview of the scientific investigations carried out in recent years. The topics discussed are forging an arc over different kinds of composite materials such as composites based on commonly available polymeric raw materials, but also composites based on biological raw materials as well as the achievable material properties comprising mechanical, electrical, structural and tribological properties. Additionally, the book is also shedding light on the construction and structuring of such composites using nature as an inspiring example.

Book excerpt: In this compilation, examples of film polymeric composites based on azobenzene polymers and metallic complexes for use in electro-optical modulators and recording media for polarization holography are considered. It is shown that the information characteristics of the investigated media are mainly influenced by the structure of the azobenzene groups (electron-donor and electron-acceptor substitutes) and by the supramolecular structure of the polymers.Following this, precise analyses of the molecular arrangement of three-dimensional crystals, two-dimensional molecular films, and interfacial particle layers of polyguanamine derivatives with a high refractive index are been performed. It is determined that the high refractive index of the polyguanamine derivatives is not caused by the chemical structure of the molecule, but is based on the packing of molecular chains or the refraction of transmitted light due to the difference in electron density between the crystalline and amorphous regions.In the closing chapter, organic-inorganic hybrid polymers are applied in different fields, including adsorption of metals from aqueous media. In this context, two organic-inorganic hybrid polymers were prepared by sol-gel method, using proportions of 1:1 and 1:3 of the monomer 1-vinylimidazole and the silane agent 3-mercaptopropyl-trimethoxysilane, respectively, in order to evaluate the proportion effect of VI and MPTMS on Hg2+ ions adsorption from an aqueous solution.

Download or read book Developments in Crystalline Polymers 1 written by David C. Bassett and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystalline or, more properly, semi-crystalline polymers continue to present major challenges and opportunities to scientists and technologists alike. On the one hand, scientific understanding of their structure and properties still lags behind that of other economically important, but less complicated materials. On the other hand, there remains very considerable potential for improving properties in systems designed for specific pur poses. Ways are only just being found of transferring inherent molecular properties (such as high modulus) to the macromolecular solid. Beyond these are many possibilities of manipulating the organization of chemical and physical textures towards desired ends. The chapters in this volume are reports, by wen-known and active researchers, on some of the important recent developments ofthese themes. Grubb begins with the fundamental and central problem of determining polymeric microstructure. Polymers sutTer by comparison with other materials in that it has not generany been possible to exploit the high resolution of the electron microscope to determine their microstructure in adequate detail. However, recently, ways have been found of studying representative lamellar textures in melt-crystallized polymers. When fully exploited these must add greatly to our detailed knowledge and provide a firmer fundamental base for future developments. Radiation damage bears the primary responsibility for restricting electron microscopy. In his chapter, Kener recounts how appreciation of this fact led him into a fascinating study of ever deeper aspects of radiation damage in polyethylene over two decades, often controversiany but invariably clarifying the basic understanding of an area now of increasing commercial importance.

Download or read book Advances in Polymers for Biomedical Applications written by Deepak Pathania and published by Nova Medcine & Health. This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers have generated considerable interest in a large number of technologically important fields such as human healthcare systems. Polymers represent a very important domain of materials and have become an integral part of day to day human life. Polymers exist in nature; they have been and continue to be an integral part of the universe. This book is intended for scientists and researchers to use in their research or in their professional practice in polymer chemistry and its biomedical applications. Multiple biological, synthetic and hybrid polymers are used for multiple medical applications. A wide range of different polymers are available, and they have the advantage to be tunable in physical, chemical and biological properties and in a wide range to match the requirements of specific applications. This book gives a brief overview about the introduction and developments of polymers for different applications. The biomedical polymers comprise not only bulk materials, but also coatings and pharmaceutical nano-carriers for drugs. The surface modification of the inorganic nanoparticles with a physically or chemically end-tethered polymer chain has been employed to overcome the problems associated with the polymers. Chemically attached polymer chains not only stabilize the inorganic nanoparticles, but also lead to photosensitivity, bioactivity, biocompatibility and pharmacological properties in the composites. Polymer encapsulated silica nanocomposites (mesoporous) have potential applications in different fields, such as optics, bio-catalysis, microelectronics bone tissue engineering, coatings cosmetics, inks, agriculture, drug release systems, diagnoses, enzyme imaging, temperature-responsive materials, and thermosensitive vehicles for cellular imaging. Polymer grafted nanosized particles are known to have excellent properties such as good dispersion ability in solvents and polymer matrices. Polymer-based controlled drug delivery systems have some specific advantages, such as improved efficiency and reduced toxicity. The incorporation of a thermoresponsive polymer layer often enhances protein absorption and specific biomolecular tagging through hydrogen bonding. As a result, the nanocomposite gets cleared from the body at a faster rate (blood residence becomes low). This book is composed of fourteen edited chapters; it is intended for scientists and researchers to use in their research or in their professional practice in polymer chemistry and its biomedical applications.

Download or read book Modification of Polymer Properties written by Carlos Federico Jasso-Gastinel and published by William Andrew. This book was released on 2016-09-14 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modification of Polymer Properties provides, for the first time, in one title, the latest information on gradient IPNs and gradient copolymers. The book covers the broad range of polymer modification routes in a fresh, current view representing a timely addition to the technical literature of this important area. Historically, blends, copolymers, or filled polymers have been developed to meet specific properties, or to optimize the cost/properties relationship. Using the gradient structure approach with conventional radical polymerization, it has been shown that it is possible to optimize properties if appropriate gradients in the composition of copolymer chains are obtained. An overview of the gradient structure approach for designing polymers has not appeared in the recent literature and this title covers the different methods used to modify properties, offering the whole range of ways to modify polymers in just one volume and making this an attractive option for a wide audience of practitioners. The approach for each chapter is to explain the fundamental principles of preparation, cover properties modification, describe future research and applications as examples of materials that may be prepared for specific applications, or that are already in use, in present day applications. The book is for readers that have a basic background in polymer science, as well as those interested in the different ways to combine or modify polymer properties. Provides an integrated view on how to modify polymer properties Presents the entire panorama of polymer properties modification in one reference, covering the essential information in each topic Includes the optimization of properties using gradients in polymers composition or structure
