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

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