摘要

The manufacturing process and the properties of graphitic foams prepared from the mesophase pitch with the addition of natural graphite were reported. It was shown that the natural graphite content can significantly affect the structure and performance of the foams such as bubble size, mesophase domain size of the ligaments and junctions and the specific compressive strength. The specific compressive strength of the foams after carbonization and graphitization was significantly increased, and the inter layer spacing decreased firstly and then increased with the increase of naturalgraphite content in the pitch. It is believed that through condition optimization the microcracks of the foams may be further reduced and so the specific compressive strength can be further increased.
