【摘要】 采用化学氧化聚合法在铝箔上合成聚吡咯 (PPy)阴极层,主要研究了表面活性剂,氧化剂浓度及反应次数对电容器性能的影响,实验发现:用PEG600 作表面活性剂。氧化剂浓度1．0mol/L,反应25次,可以制备低损耗tgδ:0．017,低ESR:14mΩ且具有优良的频率特性的固体铝电解电容器。更多还原

【Abstract】 PPy was synthesized in the aluminum film by oxidatively chemical polymerization. The influences of different kinds of surfactant, concentration of oxidizer and the times of reaction on the capacitors were investigated. The results show that : when PEG600 as surfactant, concentration of oxidizer was 1.0 mol/L, 25 times of reaction, characteristics of capacitors were: loss tangent 0.017; ESR 14m Ω. The capacitor also possesses ideal frequency characteristics.更多还原
