Overview

Description

Graphitized high purity carbon nanofibers were produced by a low temperature CVD method and subsequently annealed about twenty (20) hours under condition of inert gas at temperature 2800 °C. These products were characterized for chemical purity, and defect healing. The graphitization procedure was found to remove residual metal catalyst in the nanofibers and reduce the defects. The graphitized carbon nanoFibers have the highest graphite crystallization, the high electrical conductivity, thermal conductivity and the excellent inoxidizability. The electrical conductivity of the graphitized carbon nanoFibers is very close to that of graphite powder. And its ignition temperature can reach 800 °C
