| 摘 要：采用石墨烯／聚吡咯（rGO／PPY）復合物制備超級電容器，以彌補二者各自的不足。采用改進(jìn)Hummers法制備出氧化石墨烯（GO）。利用水合肼還原法將GO還原后得到rGO，同時(shí)采用電化學(xué)聚合法制備出PPY。最后，用電沉積法直接在不銹鋼網(wǎng)上制備出rGO／PPY復合物。得到的復合材料的比電容為209.04 F／g，顯著(zhù)高于rGO的比電容（52.42 F／g）。另外，循環(huán)1 000次后，復合材料的比電容下降18.1%，低于PPY（36.3%）。 |

| Abstract：Graphene(rGO) and polypyrrole(PPY) as good conductive materials were often used in the preparation of super capacitors. However, the usage of both rGO and PPY had its advantages and disadvantages in the preparation of super capacitors. In this paper, graphene/polypyrrole(rGO/PPY) composites were used to prepare the super capacitors. Graphene oxide(GO) was prepared by an improved Hummers method. The hydrazine hydrate reduction method is used to reduce GO to obtain graphene(rGO) while PPY was prepared by electrochemical polymerization. In the end, rGO/PPY composite was prepared directly on stainless steel net by electrodeposition. The specific capacitance of the composite material is 209.04 F/g, which was significantly higher than the capacitance of rGO(52.42 F/g). In addition, the cycle of 1000 times, the specific capacitance of the composites decreased by 18.1%, which was lower than that of the PPY (36.3%). |
