摘　　要：用超声波法合成γ相二氧化锰(γ-MnO2),然后通过循环伏安法在γ-MnO2颗粒表面电聚合聚苯胺(PANI),合成PANI/MnO2复合电极.应用恒流充放电方法测试样品的电化学性能,结果表明γ-MnO2电极材料在电流密度500 mA/g时,比电容为210 F/g,而复合材料电极比电容为500 F/g,相比γ-MnO2电极材料提高了1.38倍.The γ-MnO2 was synthesized by ultra-anclible sound method,then the PANI was electropolymerized on the surface of the γ-MnO2 granules by cyclic voltammetry method.The performance of PANI/MnO2 composited electrode was tested by constant current charge-discharge method.The results showed that the capacitance of γ-MnO2 electrode is 210 F/g in the current density of 500 mA/g.However,the composite electrode capacitance reaches 500 F/g,which capacitance increases 1.38 times.
