Grafting of polymers onto carbon nano-fiber surface and application to sensor materials

摘要

Due to their unique physical properties, such as excellent thermal and electrical conductivity, and good mechanical properties, carbon nao-fiber, such as carbon nanotube (CNT) and vapor grown carbon fiber (VGCF) have attracted considerable attention in the last ten years. In general, they are used in the form of composite where the polymer is needed as matrices. However, due to the very low surface free energy, nano-size and low bulk density, it is difficult to disperse CNT and VGCF in polymer matrix uniformly.
