摘　　要：以天然鳞片石墨为原料,首先采用改进的Hummers法合成氧化石墨前驱物,再将其用硼氢化钠还原制备得到石墨烯纳米材料,采用FTIR、XRD、TEM、SEM对氧化石墨和石墨烯进行了结构与形貌分析。结果表明,制备的氧化石墨的氧化程度较高,含有大量的含氧极性基团,如羟基、羧基、醚基等;石墨烯为二维纳米薄层片状结构,边缘有皱褶起伏。Based on the improved Hummers method,the precusor graphite oxide（GO） was synthesized from flake graphite,and then graphene was prepared by using sodium borohydride as reductant. Graphite oxide andgraphene were characterized by FTIR, XRD,TEM and SEM. The results showed that graphite oxide was high in oxidation degree and contained various oxygen functional groups such as-OH,-COOH,C-O-C,and gra- phene had two-dimensional nano-flake structure with curly edge.
