ABSTRACT:
A graphitizable carbon foam having enhanced directional thermal conductivity is provided. The mesophase portions of a mesophase pitch are aligned with each other to create an oriented mesophase pitch, which is then foamed to provide an oriented pitch foam. The pitch foam can be heated to carbonize the pitch thereby forming an oriented carbon foam. The carbon foam can be further heated to provide an oriented graphite foam.
