高性能聚吡咯复合膜的制备

用化学氧化法将聚吡咯沉积到碳纤维上，制得聚吡咯-碳纤维复合膜（PPy－CF），对复合模进行了表征。在复合膜上再电镀一层二巯基硫杂茂（DMCT），得到（PPy－DMCT－CF）复合膜，测试了该膜的电化学性能。该复合膜具有148mA·h·g-1的高储荷密度，是全固态钮电池的理想正极材料。

Polypyrrole carbon fiber (PPy-CF) composite films were prepared by chemical oxidation of ploymerization of pyrrole at the surface of CF covered teflon substrate following a layer-bylayer deposition approach. Characterization of the composite film. Polypyrrole-poly (dimercaptothiodiazole ) - carbon fiber composite film with thickness of 120μm andspecific capacity of 148mA. h. per gram (electrode) has been prepared by electroplat withDMCT onto the PPy-CF comosite film. The composite film can be used as an electrode material for secondary battery.
