石墨烯是二维结构的纳米材料，被认为有望替代硅作为新的半导体材料，因此石墨烯成为热点研究对象之一。在实际应用中石墨烯通常需要加工处理成薄膜等外形，本文将综合评述目前常用的石墨烯薄膜的制备方法，并介绍石墨烯薄膜制备方法的特点。%Graphene,a two -dimensional nanomaterial,has received extensive attention for its possibility of a potential alternative to the silicon semiconductor. Membranous graphene is an ideal form when the graphene is actually applied. The preparation methods of graphene film are reviewed and the differences between the methods are discussed in this article.
