摘要:
首先通过苯胺气体与高锰酸钾水溶液之间的气-液界面反应合成了二氧化锰/聚苯胺（MP）纳米复合材料，然后将其与氧化石墨烯（GO）水溶液混合并进行水热处理，最终得到了锰氧化物/聚苯胺/石墨烯（MPG）三元纳米复合电极材料。通过X射线衍射、拉曼光谱和扫描电子显微镜分析了产物的物质组成、结构和微观形貌。电化学测试结果表明，MPG具有较高的比电容（251 F/g，1 A/g）、理想的倍率性能（扫描速率由10 mV/s增大到200 mV/s时的比电容保持率为55%）和长循环寿命（5 A/g电流密度下，循环充放电5 000次后，其比电容保持率为81%），证实通过三元复合的方法可以有效改善锰基超级电容器电极材料的电化学性能。

Abstract:
Manganese dioxide/polyaniline （MP） composite was synthesized via a gas-liquid interfacial reaction between aniline gas and potassium permanganate aqueous solution，and then the ternary composite electrode material of manganese oxide/polyaniline/graphene （MPG） was prepared through hydrothermal treatment of the mixture of MP and graphene oxide. The chemical composition and structure were characterized by X-ray diffraction and Raman spectroscopy，and the micromorphology was observed by scanning electron microscopy. The results of electrochemical measurement manifest that MPG possesses a high specific capacitance of 251 F/g at 1 A/g，a favorable capacitance retention of 55% with scan rates from 10 up to 200 mV/s，and a high capacitance retention of 81% after 5 000 charging/discharging cycles at 5 A/g，demonstrating that the electrochemical performance of manganese-based electrode materials for supercapacitor can be effectively improved by the ternary composite method.
