摘要:通过自聚合反应及高温热处理手段,再采用化学氧化聚合法在复合物的表面自组装生长聚苯胺(PANI)纳米须,成功构筑了MnO/介孔碳(MC)/PANI三元纳米复合材料。材料的结构及其电化学性能测试结果表明:该复合材料的比电容在1.0A/g的电流密度下达到498.6F/g,显著高于MnO/MC二元复合材料的比电容(212F/g);当电流密度增加至10A/g时,比电容仍能保持352F/g。经过1000次的充放电循环,复合电极的比容量保持率为71.6%。
Manganese monoxide/mesoporous carbon(MnO/MC)composite nanowires were firstly synthesized via self-polymerization reaction and thermal treatment at high temperature by using dopamine as carbon source and MnO2 as precursor.Subsequently,self-assembling growth of polyanline(PANI)nanowhiskers on the surface of MnO/MC composite by chemical oxidative method resulted in the formation of MnO/MC/PANI ternary nanocomposite.The morphology and structure of composite were characterized and electrochemical performance of composite as supercapacitor electrode materi-als was evaluated.The results indicated the ternary composite electrode possessed a high specific capacitance of 498.6F/g at a current density of 1.0A/g and 352F/g even at a high current density of 10A/g,and still maintained 71.6%of the original capacitance after 1000 charge/discharge cycles at a current density of 1A/g.
