Carbon Nanotube-Polymer Composites (eBook, ePUB)

Manufacture, Properties, and Applications

• Format: ePub

Produktbeschreibung

The accessible compendium of polymers in carbon nanotubes (CNTs) Carbon nanotubes (CNTs)--extremely thin tubes only a few nanometers in diameter but able to attain lengths thousands of times greater--are prime candidates for use in the development of polymer composite materials. Bringing together thousands of disparate research works, Carbon Nanotube-Polymer Composites: Manufacture, Properties, and Applications covers CNT-polymers from synthesis to potential applications, presenting the basic science and engineering of this dynamic and complex area in an accessible, readable way. Designed to be of use to polymer scientists, engineers, chemists, physicists, and materials scientists, the book covers carbon nanotube fundamentals to help polymer experts understand CNTs, and polymer physics to help those in the CNT field, making it an invaluable resource for anyone working with CNT-polymer composites. Detailed chapters describe the mechanical, rheological, electrical, and thermal properties of carbon nanotube-polymer composites. Including a glossary that defines key terms, Carbon Nanotube-Polymer Composites is essential reading for anyone looking to gain a fundamental understanding of CNTs and polymers, as well as potential and current applications, including electronics (shielding and transparent electrodes), flame retardants, and electromechanics (sensors and actuators), and their challenges.
