采用微波辅助的方法制备了氧化石墨烯/多巴胺复合三维凝胶结构,经过高温煅烧后得到具有丰富孔道结构的石墨烯/裂解碳三维复合凝胶结构。通过电镜发现经过微波辅助得到的三维凝胶结构中具有大量的三维连续孔道结构,为电解液在电极材料中的传递提供了丰富的路径,经过电容测试发现该结构具有优异的电化学超级电容器性能。
A graphene oxide / dopamine three-dimensional gel structure was prepared by microwave-assisted method. After being calcined at high temperature, a graphene / pyrolytic carbon three-dimensional composite gel structure with rich pore structure was obtained. Electron microscopy showed that a large number of three-dimensional continuous pore structures in the three-dimensional gel structure obtained by microwave assisted processing provided abundant paths for the electrolyte to be transferred in the electrode material. The capacitance test showed that the structure has excellent electrochemical supercapacitor performance .
