【摘要】 以添加有机溶剂对氧化石墨烯(GO)进行改性处理，采用水热还原法得到还原氧化石墨烯(RGO-AJ)水凝胶，再分别通过冻干和晾干的方式进行干燥，得到两种不同的电极材料——RGO-AJ(冻干)和RGO-AJ(晾干)。将RGO-AJ制成电极片，组装成为超级电容器进行电化学性能测试。测试表明，在晾干处理方式下的RGO-AJ与冻干处理方式相比，拥有更好的电化学特性，且与冻干处理的样品相比，晾干处理样品的表面更为光滑和平整。更多还原

【Abstract】 The graphene oxide(GO) was modified by adding organic solvents, and reduced graphene oxide(RGO-AJ) hydrogel was obtained by hydrothermal reduction method.Then, two different electrode materials, RGO-AJ(freeze-dried) and RGO-AJ(dried),were obtained by freeze-drying and air-drying respectively.RGO-AJ was used as electrodes and assembled into supercapacitors for electrochemical performance test.The results showed that RGO-AJ obtained by drying in air had better electrochemical performance compared with the freeze-drying samples, because it had smoother and flat surface.更多还原
