The synergetic relationship between the length and orientation of carbon nanotubes in direct spinning of high-strength carbon nanotube fibers

Floating catalytic chemical vapor deposition (FCCVD) is an attractive method for synthesizing carbon nanotube (CNT) fibers of high strength, toughness and electrical conductivity. During the process of CNT fibers synthesis, the assembly structure, such as the CNT orientation, CNT length, and the inter-tube particle impurity inside the CNT fibers, are key factors to determine the mechanical properties of CNT fibers. However, the regulation...
