摘　　要： 石墨烯是一种具有二维平面结构的碳纳米材料,特殊的结构决定了它具有许多优异的物化性能。近年来,人们在以石墨为原料制备石墨烯方面取得了积极的进展,为石墨烯的基础研究和下游应用开发提供了原料保障。以石墨为原料制备石墨烯是最为经济简单的方法。本文对近3年来以石墨为原料制备石墨烯的6种方法(化学氧化-还原法、溶剂热法、液相剥离法、电化学剥离法、球磨法以及超临界流体剥离法)作了综述并讨论了各方法的优缺点。 Graphene, a recently discovered carbon nanomaterial with carbon atoms tightly packed into a two dimensional honeycomb lattice, possesses diverse novel and unique physical and chemical properties. In recent years, different routes to prepare graphene by exfoliation of graphite have been developed, which provides a new material for the basic research and applications. This review introduced six methods including reduction of graphene oxide, liquid-phase exfoliation, solvothermal exfoliation, electrochemical approaches, ball-milling of graphite and supercritical fluid exfoliation. Relative merits of these methods were compared and analyzed.
