Abstract：background:Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms with sp2 hybrid orbitals and hexagonal honeycomb lattices.It is the thinnest but hardest nanomaterial with the best electrical conductivity. Mass production of graphene is the core of promoting the industrialization of graphene. Research status:One of the key issues is the preparation method of graphene.The existing preparation methods mainly focus on the chemical direction, but many of its inherent physical findings come from graphene prepared by micromechanical exfoliation.Research purposes:This article comprehensively introduces the properties and peeling mechanism of graphene, expounds the research progress of graphene preparation by ultrasonic, ball milling, and three-roll milling and peeling method, compares their respective characteristics and problems, and prospects its mechanical methods. The future development prospects of graphene preparation.
