Book Description

This book provides readers with a comprehensive toolbox for dispersing single-walled and multiwalled carbon nanotubes in thermoplastic polymer matrices. The book starts with an overview of all known techniques for dispersing CNTs in thermoplastic polymers and then concentrates on one of the most versatile techniques known nowadays: the so-called latex technology. Also discussed are the basic principles of this latex technology, the role of the matrix viscosity on percolation threshold, the importance of the intrinsic CNT quality, the use of "smart" surfactants facilitating electron transport in the final composite, the preparation of highly loaded master-batches, which can be diluted with virgin polymer by melt-extrusion, and some promising potential applications.

Reviews

"These authors are leading researchers and have done a great service to the community by capturing the current understanding of carbon nanotube polymer nanocomposites. Active research in industry and academia alike will find this book a timely and valuable resource, particularly as it pertains to electrical conductivity of these fascinating materials."
—Prof. Karen I. Winey - University of Pennsylvania, USA

"Carbon nanotubes are promising conductive fillers for a variety of applications from organic electronics to electrostatic dissipation of composites. This book provides a valuable review on the processing of nanotube dispersions and composites. An emphasis is given to the "latex technology", one of the most efficient approaches to achieve conductive networks of nanotubes. This book will be of great interest to a broad readership in chemistry, physics and materials science in both academia and industry."
