Fully revised and expanded, this second edition of A. Blythe's successful title on electrical properties of polymers covers both the fundamental and recent developments in this growing area. This book provides a broad and comprehensive account on the topic, describing underlying physical principles and synthesis through to emerging technologies. The new edition provides particular emphasis to the new generation of conductive polymers. Emerging uses of polymers in industrial applications are described and cover topics such as light-emitting diodes, flexible polymers and soft electronics. Written in an accessible style, without complicated theory, this book combines key concepts with applications. With the inclusion of further reading material provided at the end of each chapter for interested readers, this book is an authoritative guide to advanced-level undergraduates and graduates studying polymer, materials and physical sciences. It will also be of significant interest to researchers working in this evolving field.
