| Abstract: | 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. |
