Nanotube super fiber materials refer to different forms of macroscale materials with unique properties constructed from carbon nanotubes. These materials include nanotube arrays, ribbons, scrolls, yarn, braid, and sheets. Nanotube materials are in the early stage of development and this is the first dedicated book on the subject. Transitioning from molecules to materials is a breakthrough that will positively impact almost all industries and areas of society. Key properties of superfiber materials include flexibility and fatigue resistance, high energy absorption, good electrical and thermal conductivity, high maximum current density, and reduced skin and proximity effects. These properties enable dozens of applications including replacing copper wire in power conduction, EMI shielding, nerve scaffolding, and energy storage. Superfiber materials are used in coax cable, carbon biofiber, bullet-proof vests, impact resistant glass, wearable antennas, biomedical micro devices, biosensors, self-sensing composites, supercapacitors, superinductors, hybrid superconductors, and reinforced elastomers. This book covers processing, properties, and applications. Processing discusses nanotube synthesis and macro-scale material formation. Properties cover mechanical, electrical, chemical, and other properties of nanotubes and macroscale materials. Applications discusses a broad array of uses. Explores production and application of macro-scale materials made of nanoscale particles.
