炭泡沫的制备、性能及应用

Preparation,Performances and Applications of Carbon Foams

炭泡沫是具有广阔应用前景的新型炭材料,自出现起就成为炭材料研究中的热点。以中间相沥青基炭泡沫为重点,介绍了炭泡沫的发展历史和研究进展,总结了现有炭泡沫制备技术,包括发泡剂发泡法、模板法、中间相沥青自发泡法和限空间法等,概述了炭泡沫的性能和应用前景,并展望了其发展方向。

Carbon foams are new carbon materials with many potential applications. They have been the focus of carbon materials since they were developed. Based on the mesophase-pitch-derived carbon foams, this article introduces the history and development of carbon foams, briefly reviews their preparation methods such as foaming by foaming agent method, foaming by template method, self-foaming ofmesophase pitch method, size-restriction foaming method and so on, summarizes their performances and potential applications, and makes a forecast for their development.
