摘　　要：Graphene是一种严格的二维晶体材料,因其具有独特的结构和性能,已迅速成为国际新材料领域的研究前沿和热点.文章详细介绍了近几年发展起来的Graphene的化学制备方法,如SiC高温热解外延法、过渡金属催化外延法、化学修饰分散/还原法等,并对各种方法的特点,研究现状及应用前景进行了评述.Graphene, as an ideal realization of two-dimensional crystals, has a promising future due to its unique electronic and physical properties. Many methods have been exploited to prepare high quality Graphene. Three main methods are reviewed, including the thermal decomposition of SiC （carbide） crystal surfaces, catalytic decomposition of hydrocarbon molecules on noble metal crystal surfaces, and chemically modified dispersion/reduction. The characteristics, recent development, and application prospects of each method are also discussed.
