摘 要:
采用恒电流法在聚吡咯（PPy）和聚苯胺（Pani）的相应单体溶液中制备了PPy和Pani的复合型导电高分子膜电极．根据循环伏安曲线、充放电曲线和电化学阻抗谱，研究了超级电容器的电容性能．结果表明，聚合顺序对复合型导电高分子膜电极的电容性能有很大影响，以PPy为底层的复合型电极的电容性能远高于其他复合型电极或单层膜电极．不锈钢／PPy／Pani和不锈钢／PPy／Pani/PPy电极的比电容分别高达196．08F／g和212．53F／g．[著者文摘]

Abstract:
Conducting composite polymers consisting of Polypyrrole （PPy） and Polyaniline （Pani） were synthesized successfully using galvanostatic technique in the corresponding monomer solution. The properties of electrochemical super-capacitor assembled with conducting polymers were investigated by cyclic voltammetry, charging-discharging cycles and electrochemical impedance spectroscopy. The result has shown that the capacitor properties depend heavily on the deposit order： the composite polymers with PPy as the primer have better capacitive than that with Pani as the primer. The specific capacitance of stainless steel/PPy/Pani and stainless steel/ PPy/Pani/PPy electrodes is far higher （up to 196.08 F/g and 212.53 F/g） than that of pure conducting polymers or other composite polymers.[著者文摘]
