摘 要:采用石墨烯/聚苯胺(rGO/PANI)复合物制备超级电容器,以弥补二者各自的不足。改进了Hummers法制备氧化石墨烯(GO)。采用原位聚合法制备出PANI,最后利用水热法制备出rGO/PANI复合物。得到的复合材料的比电容最高值达198 F·g-1,明显比rGO的比电容(52 F·g-1)值高。此外,循环1 000圈后,复合材料的电容量衰减5%。

Preparation and Electrical Properties of 3D-Graphene/Polyaniline
ZHANG Kai, WANG Qi-guan* (Xi'an Technological University, Xi`an 710021, China)
Abstract:Supercapacitors were prepared using graphene/polyaniline(rGO/PANI) composites to compensate for their respective deficiencies. Graphene oxide(GO) was prepared by the modified Hummers method. PANI was prepared by in-situ polymerization, and finally rGO/PANI composite was prepared by hydrothermal method. The resulting composite has a specific capacitance of up to 198 F·g-1, which is significantly higher than the specific capacitance of rGO(52 F·g-1). In addition, after 1 000 cycles, the capacitance of the composite material was only attenuated by 5%.
