中文摘要：

氧化石墨热剥离法制备石墨烯，将还原过程由传统的液固相变为气固相，这样减少了影响还原的因素，简化了工艺。在避免使用相对昂贵的液体还原剂的同时，解决了液固还原难以避免的因自重构造成的石墨烯再团聚问题。该法制备的石墨烯层数少，并为规模化和可控地制备石墨烯提供了有利条件。综合近年来研究成果，对该法涉及的剥离机理，以及氧化和热剥离还原两部分的各种影响因素进行分析和讨论，并结合该方法所存在的不足对未来研究进行了展望。

英文摘要：

The reduction of graphite oxide was the most possible method to achieve mass production of gra-phene.A number of methods have been developed to exfoliate graphite oxide,and each method has its own ad-vantages and disadvantages.Thermal exfoliation was the most economical way to obtain large quantities of gra-phene especially functional graphene.The exfoliation mechanism was mainly based on that the sudden expan-sion gases evolved into the spaces between graphene sheets during the heat-treatment process of graphite oxide. Thermal exfoliation can be realized when the sudden expansion gases pressure overcomed the attractive van der Waals inter-actions between layers.However,different oxidation and reduction processes make the functional graphene with different properties.In this paper,current research was reviewed,the mechanism of the oxida-tion and thermal exfoliation was discussed,which may contribute us to effectively use the controllable factors to partially control the preparation of functional graphene.
