Abstract: Carbon foam, a new type of sponge-like carbon materials, has attracted considerable interest due to its special properties such as low density, high temperature tolerance and high mechanical strength. In this paper, the raw and preparation method of carbon foam was summarized. Influence of experiment factors on the structure and application performance of carbon foam was systematically interpreted. The future development of carbon foams is proposed.

Key words: carbon foam, preparation methods, structure, property, application
