The morphologies of nano carbon growing in-situ by catalytic chemical vapor deposition

摘要：

　　In order to improve surface characteristics of carbon fibers,using nickel granules as catalysts,nano carbon with different morphologies was deposited in-situ on the surface of carbon fibers by the method of Chemical Vapor Deposition (CVD).The observations by Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) indicated that keeping the excellent performance of plating nickels catalyst and a suitable deposition rate of Pyrogenation Carbon (PyC) are the key factors for getting Carbon Nanotube and Carbon Nanofiber (CNT/CNF).In this experiment,the optimum operation conditions are:plating time at 5min,deposition temperature at 1173K,deposition time at 2 hours,flow of C3H6,H2 and N2 at 30,200 and 400ml/min respectively,deposition pressure at 700-1000Pa.Evolution rules of nano carbon are explained in growth mechanism of Catalytic Chemical Vapor Deposition (CCVD).
