This book summarizes recent technical accomplishments in the area of polymer nanocomposites, focusing on their preparation, properties, characterization, and applications. After an introductory chapter overviewing the basics of nanoscience and nanotechnology, chapters cover topics such as interfacial interactions in layered silicate polymer nanocomposites, polysiloxane-based polymer nanocomposites, multiwall carbon nanotube reinforced polyester nanocomposites, and clay-containing styrenic compounds. Contributors are researchers from industry, academia, and government and private labs around the world. The book will be useful for advanced students and polymer technologists and researchers working in polymer nanocomposites. Zaikov is affiliated with the Russian Academy of Sciences.
