Preparation and Morphological Study of Coal-tar-based Carbon Foam

摘要

A novel process for fabricating coal-tar pitch derived carbon foam was introduced. The coal-tar based mesophase pitch was characterized by Infrared Ray Spectrum (IR) and Wide Angle X-ray Diffraction (WAXD). SEM was used for the morphological study of carbon foam. The results showed that the pitch foam with pores of 300～500 μ m and low density of 0.2～0.5g/cm~(-3) could be successfully fabricated and further carbonized and graphtized to obtain a novel carbon foam.
