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.

Pas de titre par Guimaraes,, Alberto Passos. Publication : [S.l.] Springer 2009 . 224 p. , The book deals with the novel field of Nanomagnetism, the study of magnetic samples that have at least one dimension in the nanoscopic range. Nanomagnetism has helped to shape the modern world through the contribution of this discipline to the rapid evolution of high- density magnetic recording. This process has made the hard-disk-equipped personal computer a part of our lives. The approach of this succinct book is to emphasize general principles and mechanisms that are relevant for the understanding of the intriguing properties of nanomagnetic objects, including thin films, nanoparticles, nanowires, nanodisks and nanorings. 25 cm. Date : 2009 Disponibilité : Exemplaires disponibles: La bibliothèque des Sciences Exactes et Naturelles (1),
