Product Overview
The CVD method for preparing carbon nanotubes is widely used because of its advantages such as mature method and high yield. However, the preparation of carbon nanotubes by CVD method often requires the introduction of a catalyst, and the nanotubes grow gradually along the radial and axial directions with the catalyst particle as the center. The difficulty of removing the catalyst has become an important factor restricting the purity of the carbon tube, which will limit the application of the carbon tube to a certain extent. Graphitized carbon tube is the ordinary carbon tube in the inert atmosphere of high temperature treatment, can effectively remove the catalyst and other impurities, effectively improve the purity of the carbon tube, reduce defects, effectively improve its microstructure, in order to obtain good electrical, thermal, mechanical and other properties. The higher the degree of graphitization, the better the crystallinity, thermal stability and electrical conductivity of the carbon nanotubes are generally better.
