摘　　要：石墨烯优异的电学、光学和力学性能掀起了多领域的研究热潮,其制备方法也成为重点研究方向。机械剪切剥离法成本低,操作简单,且不会破坏石墨烯本征特性等特性,备受研究者关注。文中介绍了石墨烯的性质和剥离机理,并阐述了机械剥离法中低能纯剪法、三辊磨剥法和球磨法,比较了各方法的特点及面临的问题。由于球磨法是目前最有望大规模制造石墨烯的方法,故文中优化了球磨工艺,提出了一种磨盘式结构球磨机。该球磨机有效避免了磨球之间的撞击力,保护石墨晶格免于破环,提高了剪切效率。The excellent electrical,optical and mechanical properties of graphene have set off a research boom in various fields,and its preparation method has become the focus of research.Mechanical shear stripping method has attracted much attention because of its low cost,simple operation,and no damage to the intrinsic properties of graphene.This paper introduces the properties and stripping mechanism of graphene,and reviewes the low energy pure shearing method,the three-stick grinding and stripping method and the ball milling method in the mechanical peeling method,and compares their respective characteristics and problems.Since the ball milling method is currently the most promising method for producing graphene on a large scale.the ball milling process is optimized in this paper,and a grinding disc structure ball mill is proposed.The ball mill effectively avoids the impact force between the grinding balls,protects the graphite lattice from being broken,and improves the shearing efficiency.
