摘　　要：为改善石墨烯加工性能,在石墨烯掺杂金属银。以低成本可膨胀石墨粉为原料,利用氧化还原反应在氧化石墨烯上负载银,确定了该合成反应的工艺条件。X射线衍射、红外光谱分析、拉曼光谱、紫外可见分光光度分析、扫描电子镜等手段对氧化石墨烯负载银的内部结构进行表征。结果显示:改性后的氧化石墨烯热稳定性更好,加工性能更加优越。石墨烯负载银电化学性能的伏安循环法实验揭示,石墨烯负载银具有更优良的电学性能。In order to improve the processing performance of graphene, graphene oxide was loaded silver（GO/Ag）. Silver was loaded on graphene oxide by redox reaction at a low cost of expandable graphite powder as raw material. The process conditions of the synthesis reaction was determinated. GO/Ag was tested by X ray diffraction, infrared spectroscopy, Raman spectroscopy, UV Vis, SEM and so on. From the expermiental results, it can be concluded that the modified graphene oxide has a good thermal stability, processing performance is more superior. It has more excellent electrical properties of GO/Ag by cyclic voltammetry.
