Conducting polymers with micro or nanometer structure par Wan, Meixiang. Publication : New York Springer 2008 . 170 p. , Conducting Polymers with Micro or Nanometer Structure describes a topic discovered by three winners of the Nobel Prize in Chemistry in 2000: Alan J. Heeger, University of California at Santa Barbara, Alan G. MacDiarmid at the University of Pennsylvania, and Hideki Shirakawa at the University of Tsukuba. Since then, the unique properties of conducting polymers have led to promising applications in functional materials and technologies. The book first briefly summarizes the main concepts of conducting polymers before introducing micro/nanostructured conducting polymers dealing with their synthesis, structural characterizations, formation mechanisms, physical and chemical properties, and potential applications in nanomaterials and nanotechnology. The book is intended for researchers in the related fields of chemistry, physics, materials, nanomaterials and nanodevices. Meixiang Wan is a professor at the Institute of Chemistry, Chinese Academy of Sciences, Beijing. 25 cm. Date : 2008 Disponibilité : Exemplaires disponibles: La bibliothèque des Sciences Exactes et Naturelles (1),

Polymer nanocomposites by emulsion and suspension polymerization   Publication : [S.l.] Royal Society of Chemistry 2010 . 332 p. , 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. 24 cm.

Progress in monomers, oligomers, polymers, composites and nanocomposites   Publication : [S.l.] Nova Science Pub Inc 2009 . 401 p. , Knowledge is the foundation for mankind's most successful ventures. Today there is a visible shift in science, where people have shifted from chemistry to biology, and from biology to medicine. Everybody wishes to be wealthy and healthy. Jonathan Swift once said, "Everybody wants to live longer but nobody wants to be old." Still, the role of polymer chemistry (pure and applied sciences) is very prominent in the world of science today, but it is heading away from polymers and polymer blends towards composites and nanocomposites. It allows for the creation of new materials with unique properties and new possibilities. This a second edition on this subject. If we measure the world's production of materials by volume and not by weight, then we find that it equals the production of iron, cast, steel, and coloured metals together. This volume equals 250-270 million cubic metric of material per year. It is important to note that the rate of production of polymers is overcoming the rate of production of metals by 30-40%. Mankind used to live in the Stone Age, then the Iron Age, then the Bronze Age, and now it has come to be the Age of Polymers (leaning heavily towards composites and nanocomposites). There are reviews and essays, according to the opinions of editors, that are helping to further develop polymer science and assist in solving practical applications (new materials with improved properties). 27 cm.

Smart hydrogel modelling par Li,, Hua. Publication : [S.l.] Springer 2009 . 369 p. , This is the first monograph of its kind, where a comprehensive and systematic description of modeling and simulation of the smart polymer hydrogels in BioMEMS environment is provided. It will cover the development of the models in form of nonlinear coupled partial differential governing equations for the smart hydrogels. Further, benchmark results, for simulation and prediction of responsive behaviour of the smart hydrogels to solution pH, externally applied electric voltage, environmental temperature, glucose/carbohydrates and salt concentration/ionic strength that are basic stimuli in common BioMEMS devices, are also documented. Finally, it is written in as simple a manner as possible, such that it will make informative and easy reading for the expert, and concurrently it can serve as a rich reference source for a graduate student intending to work in this area. 25 cm. Date : 2009 Disponibilité : Exemplaires disponibles: La bibliothèque des Sciences Exactes et Naturelles (1),
