摘 要:采用石墨烯/聚苯胺(rGO/PANI)復合物制備超級電容器,以彌補二者各自的不足。改進(jìn)了Hummers法制備氧化石墨烯(GO)。采用原位聚合法制備出PANI,最后利用水熱法制備出rGO/PANI復合物。得到的復合材料的比電容最高值達198 F·g-1,明顯比rGO的比電容(52 F·g-1)值高。此外,循環(huán)1 000圈后,復合材料的電容量衰減5%。 |

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%. |
