摘　　要：采用化学氧化聚合法在铝箔上原位聚合聚吡咯阴极层,研究了不同氧化剂、4-硝基酞酸加入方式对聚吡咯电容器性能的影响。结果表明:添加4-硝基酞酸明显降低了电容器的漏电流,制备出tanδ为0.012(100Hz),IL小于0.8μA,且具有良好频率特性的固体片式铝电解电容器。Polypyrrole was synthesized on the aluminum film by oxidative chemical polymerization. The influences of different kinds of oxidizer and way of adding 4-nitrophthalic acid on the capacitor properties were investigated. The results show that the capacitor with loss tangent 0.012（100 Hz）, leakage current IL〈0.8 μA is successfully prepared. The capacitor also possesses ideal frequency characteristics.
