中文摘要: 采用Hummers法制备氧化石墨，化学分散法制备羧基功能化石墨烯。采用FT-IR、XRD对产物进行表征；用静电自组装法将其与壳聚糖(CS)复合制备复合膜，对复合膜的荧光性能及其修饰玻碳电极对葡萄糖的电催化氧化还原性能进行了研究。结果表明：制备的功能化石墨烯含有羧基；壳聚糖-石墨烯复合膜具有光致发光性能；复合膜修饰玻碳电极对葡萄糖具有良好的电催化氧化还原性能。
Abstract:Carboxyl functionalized graphene was prepared by chemical dispersion and characterized by FT-IR and XRD. Composite membrane of carboxyl functionalized grapheme with chitosan (CS) was prepared via electrostatic self-assembly. The fluorescence properties of the composite film and the electro-catalytic oxidation-reduction properties of the composite membrane modified glassy carbon electrode for glucose were studied. Results showed that the functionalized graphene was successfully prepared and the composite membrane showed good photoluminescence performance. Glassy carbon electrode modified with the composite membrane showed good performance of electro-catalytic oxidation-reduction for glucose.
