文摘

Carbon nanotubes (CNTs) were synthesized by the electric heating catalytic chemical deposition method (CCVD) using acetylene (C₂H₂) as the carbon source and nitrogen (N₂) as carrier gas, and nickel catalyst was loaded by electroplating. The electric heating method, as a new method, electrifies the carbon fiber directly by using its conductivity. The morphology and structure of CNTs were characterized by SEM and TEM, and the surface properties of carbon fibers before and after the growth of CNT were characterized by Raman spectroscopy. The experimental results show that the electric heating method is a new method to produce CNT, and can grow a large number of CNTs in a short time, the crystallization degree and surface average crystallite size of carbon fiber increased after the growth of CNT on it. In addition, electroplating loading catalyst can also be used as an ideal loading way, which can control the number, shape, and distribution of nickel particles by controlling the plating time.
