摘　　要：为提高石墨烯的应用价值,本研究采用叶绿素铜钠对还原氧化石墨烯(RGO)进行非共价键改性,改性后的石墨烯在水溶液中具有良好的分散性能。采用红外光谱对产物结构进行了表征;通过紫外光谱对比分析了不同比例的复合物,发现在叶绿素铜钠和石墨烯之间存在较强的电子效应;热重分析(TGA)表明非共价的叶绿素铜钠-石墨烯复合物中叶绿素铜钠的含量比较高;扫描电镜(SEM)考察了叶绿素铜钠-石墨烯复合物的形貌特征。The sodium copper chlorophyllin was used to modify graphene,and the modified graphene had good dis persion performance in aqueous solution. The structures of products were characterized by FT-IR. Strong electronic effects between chlorophyllin and graphene was found from UV-vis absorption. The thermal gravity analysis（TGA） showed that the weight percentage of sodium copper chlorophyllin was relatively high. The morphology features were investigated by SEM.
