摘要
石墨烯具有各种优异性能,使其成为当前研究的热点,但如何大规模、高质量、低成本的制备石墨烯是当前亟待解决的问题,利用超临界流体插层-剥离制备石墨烯是有望解决上述问题的新方法。对利用超临界流体插层-剥离制备石墨烯的过程进行了综述,包括超临界流体的选择、辅助方法(超声辅助、流体剪切辅助、添加分子楔)、超临界流体膨胀速率的影响、重复实验、实验参数的影响等,对石墨烯的表征技术进行了概述,并对该技术存在的问题进行了总结。
Graphene has a variety of excellent properties make it become the focus of current research,but how to large-scale,high quality and low cost of the preparation of graphene is a problem to be solved,the method of using supercritical fluid intercalation-exfoliation to preparation of grapheme is a promising way to solve the above problems.The preparation process of graphene by using supercritical fluid intercalation-exfoliation was summarized,including supercritical fluid selection,assistance method（ultrasonic,stirring,Adding molecular wedge）.The effect of supercritical fluid expansion rate,repeated experiments,the effects of experimental parameters,etc,the characterization methods of graphene were given,and the problems of the technology were summarized.
