Download or read book Polymer Nanocomposites by Emulsion and Suspension Polymerization written by Vikas Mittal and published by Royal Society of Chemistry. This book was released on 2010-09-30 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer nanocomposites revolutionized research in the composites area by achieving the nanoscale dispersion of the inorganic filler (clay platelets) in the polymer matrices after suitable surface modifications of the filler phase. A large number of polymer matrices were tried and nanocomposites with varying degrees of successes were achieved with these polymer systems. The majority of the synthesis are carried out by melt blending which frequently result in the full exfoliation of the filler. However, advanced techniques provide a number of advantages as compared to the melt blending and lead to more uniform composites with enhanced properties. There are a number of recent advances in these methods such as the use of reactive surfactants, modified initiators, advanced clay surface modifications, use of a variety of fillers, inverse polymerization, and miniemulsion polymerization methods which have further led the generation of advanced exfoliated nanocomposites. Until now, most of the published research has been scattered throughout the literature. This book provides a single comprehensive source of information about one of the most important facets of polymer nanocomposites technology: synthesis in emulsion and suspension. These polymerization methods lead to the generation of the well delaminated polymer nanocomposites with a wide range of polymer matrices. This book serves as both a professional reference for experienced researchers and a valuable text for newcomers to the field. It makes the reader aware of the potential commercial use of these recent developments.

Available in PDF, EPUB and Kindle. Book excerpt: Nanocomposite Structures and Dispersions deals with the preparation of gelled, branched and crosslinked nanostructured polymers in the solution free radical polymerization and controlled/living radical polymerization and polymer and composite nanoparticles and nanostructures in disperse systems, the kinetics of direct and inverse disperse polymerizations (microemulsion, miniemulsion, emulsion, dispersion and suspension polymerization), the bottom-up approach building of functionalized nanoparticles, modelling of radical microemulsion polymerization, the characterization of traditional and non-traditional polymer dispersions, the collective properties of nanomaterials and their (bio)applications.This book is designed to bridge that gap and offers several unique features. First, it is written as an introduction to and survey of nanomaterials with a careful balance between basics and advanced topics. Thus, it is suitable for both beginners and experts, including graduate and upper-level undergraduate students. Second, it strives to balance the colloidal aspects of nanomaterials with physical principles. Third, the book highlights nanomaterial based architectures including composite or hybrid conjugates rather than only isolated nanoparticles. A number of ligands have been utilized to biodecorate the polymer and composite nanocarriers. Finally, the book provides an in depth discussion of important examples of reaction mechanisms of bottom-up building of functionalized nanoparticles, or potential applications of nanoarchitectures, ranging from physical to chemical and biological systems. - Free radical (controlled) polymerization, branching, crosslinking and gelling - Kinetics and mechanism of polymer nanoparticles formation - Modelling of radical polymerization in disperse systems - Polymer, composite and metal nanoparticles, nanostructures and nanomaterials - Smart nanostructures, biodecorated particles, nanocarriers and therapeutics

Download or read book Surfactants and Polymers in Aqueous Solution written by Krister Holmberg and published by Wiley. This book was released on 2002-11-22 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many industrial formulations such as detergents, paints, foodstuff and cosmetics contain both surfactants and polymers and their interaction govern many of the properties. This book is unique in that it discusses the solution chemistry of both surfactants and polymers and also the interactions between the two. The book, which is based on successful courses given by the authors since 1992, is a revised and extended version of the first edition that became a market success with six reprints since 1998. Surfactants and Polymers in Aqueous Solution is broad in scope, providing both theoretical insights and practical help for those active in the area. This book contains a thorough discussion of surfactant types and gives information of main routes of preparation. A chapter on novel surfactants has been included in the new edition. Physicochemical phenomena such as self-assembly in solution, adsorption, gel formation and foaming are discussed in detail. Particular attention is paid to the solution behaviour of surfactants and polymers containing polyoxyethylene chains. Surface active polymers are presented and their interaction with surfactants is a core topic of the book. Protein-surfactant interaction is also important and a new chapter deals with this issue. Microemulsions are treated in depth and several important application such as detergency and their use as media for chemical reactions are presented. Emulsions and the choice of emulsifier is discussed in some detail. The new edition also contains chapters on rheology and wetting. Surfactants and Polymers in Aqueous Solution is aimed at those dealing with surface chemistry research at universities and with surfactant formulation in industry.

Download or read book Fundamentals of Latex Film Formation written by Joseph Keddie and published by Springer Science & Business Media. This book was released on 2010-02-18 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has emerged out of our long-time research interests on the topic of latex film formation. Over the years we have built up a repertoire of slides used in conference presentations, short courses and tutorials on the topic. The story presented in this book has thereby taken shape as it has been told and re-told to a mix of academic and industrial audiences. The book presents a wide body of work accumulated by the polymer colloids community over the past five decades, but the selection of examples has been flavoured by our particular experimental interests and development of mathematical models. We intend the book to be a starting point for academic and industrial scientists beginning research on latex film formation. The emphasis is on fundam- tal mechanisms, however, and not on applications nor on specific effects of formu- tions. We hope that the book consolidates the understanding that has been achieved to-date in the literature in a more comprehensive way than is possible in a review article. We trust that the reader will appreciate the fascination of the topic.

Download or read book An Introduction to Polymer Colloids written by Françoise Candau and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of interest in the subject of Polymer Colloids over the last twenty five years or so has been very large resulting now in major international conferences on an annual basis and many national ones as well. The interest stems not only from the wide range of applications of these materials but also from a curiosity as to the mechanism of formation and their growing use as model particles to investigate fundamental aspects of physics and chemistry. In July 1988 a NATO Advanced Study Institute was held in Strasbourg, France, at the Centre St. Thomas. As an educational introduction to this I nstitute a series of eight lectures was given to cover the fundamental aspects of the subject. These eight lectures have now been compiled into an Introductory Text covering, emulsion poly merization, dispersion polymerization, inverse emulsion polymerization, the morphology of copolymer latices, the colloidal properties of latices, characterization methods and rheology. It is hoped that these will serve a wide audience, undergraduates, graduate-students and research workers, both in industry and academe. The chapters all contain review material up to date at the time of publication. fhe 1988 NATO Advanced Study I nstitute was made possible by a grant from the NATO-AS I programme and the following companies: BASF, Ludwigshafen, West Germany The Dow Chemical Company, Michigan, USA Dow Chemical Rheinwerk GmbH, Rheinmunster, West Germany ICI PLC, Runcorn, England S.
