机械法制备石墨烯的研究进展

Research Progress in Preparation of Graphene by Mechanical Exfoliation

作为近年来的材料"明星"石墨烯,其制备方法的研究大多集中在化学方向,然而其许多本征物性的发现却来自于微机械剥离法制备的石墨烯。本文全面介绍了各类机械法诸如胶带法,"纳米铅笔"法,超薄切片法,超声波法,行星式球磨法,搅拌球磨法,低能纯剪切磨法和三辊磨剥法制备石墨烯的研究进展,评述了以上制备方法的特点及其面临的问题,并展望了机械法制备石墨烯的未来发展前景。

The preparation methods of graphene as a ＂star＂ material were mainly tended to chemical ways in recent years. However, many intrinsic physical properties of graphene were discovered from the graphene that was prepared by micro-mechanical peeling method. In this review, the recent ad- vances in all kinds of mechanical exfoliation methods which contained ＂scotch tape＂ method,＂nanopen- cil＂ method, ultrathin sections method, ultrasonic method, planetary ball milling method, stirred ball milling method, low energy pure shear milling method and three-roll milling method were highlight- ed, and the advantages and disadvantages of these methods were analyzed. The development trend of mechanical exfoliation was prospected.
