Understanding the properties of polymer carbon nanotube (CNT) composites is the key to these materials finding new applications in a wide range of industries, including but not limited to electronics, aerospace and biomedical/bioengineering. This book provides in-depth coverage of the preparation, characterization, properties and applications of these technologically interesting new materials. Part One covers the preparation and processing of composites of thermoplastics with CNTs, with chapters covering in-situ polymerization, melt processing and CNT surface treatment, as well as elastomer and thermoset CNT composites. Part Two concentrates on properties and characterization, including chapters on the quantification of CNT dispersion using microscopy techniques. In Part Three, the applications of polymer/CNT composites are reviewed, with chapters on specific applications such as in fibers and cables, bioengineering applications and conductive polymer CNT composites for sensing. This book is an essential reference for scientists, engineers and designers in high-tech industries and academia with an interest in polymer nanotechnology and nanocomposites.
