Expanded graphite preparation technology were reviewed with 48 references .Two commonly used preparation methods were introduced in detail: ( 1 ) The expandable graphite were prepared by oxidation and then expanding process from natural flake graphite .( 2 ) The explosion of expanded graphite:The oxidation and heat expansion can be processed simultaneously .The advantage and disad-vantage of different methods were analysed .The prospect of preparation process of expanded graphite is presented .%综述了膨胀石墨制备方法的研究现状,重点阐述了两种常用制备方法:(1)以天然鳞片石墨为原料,先经氧化制得可膨胀石墨,再经膨化处理得膨胀石墨;(2)将氧化和膨胀同时进行的爆炸法.分析了不同制备方法的优劣.并对膨胀石墨的制备工艺进行了展望.参考文献48篇.
