摘要
在常温常压条件下制备了氧化石墨烯/多巴胺复合三维凝胶结构,并通过高温煅烧得到了石墨烯/裂解炭复合结构。采用扫描电镜和比表面积测试发现裂解炭的包覆有效降低了石墨烯片层的团聚,得到的材料表现出了较大比表面积;通过恒流充放电测试发现所制备的材料具有较好的电容性能。
Three dimensional graphene/dopamine aerogel was prepared in the nature condition and the graphene/carbon composited aerogel was obtained with the followed calcination.The SEM and BET results showed that the undesirable agglomeration of graphenen layers was significantly reduced and a high specific surface area was obtained.The as-prepared sample performed a very high specific capacitance.
