C_(60)-聚吡咯复合膜的制备及其电化学性质

Electrochemistry of C_(60)-polypyrrole composite films

制备了C60与聚吡咯的单层及双层复合膜。应用电化学分析法研究了它们的循环伏安性质以及石英晶体微天平性质。发现无论是单层还是双层C60聚吡咯薄膜的电化学行为都与C60固态薄膜和聚吡咯薄膜的电化学性质不同。结果表明,多层C60聚吡咯薄膜的电化学性质不如单层C60聚吡咯薄膜的稳定。且单层C60聚吡咯薄膜的电化学性质基本不受C60含量的影响。

C_(60)-polyprrole composite films were synthesized and their electrochemical properties were studied by cyclic voltammometer and electrochemical quartz crystal microbalance. It was found that the electrochemical behaviour of monolayer or double layer composite films were different from that of C_(60) film or polypyrrole. The results demonstrate that the electrochemical behaviour of the composite films was unstable when the layers were increased. The electrochemical behaviour of monolayer composite films was not influenced by C_(60) contend.
