摘　　要：采用循环伏安法和石英晶体微天平 (QCM)技术对四氨基钴酞菁 (CoTAPc)在金电极上的聚合成膜过程进行了研究 ,考察了扫描速度、溶剂、支持电解质及单体浓度对其成膜过程的影响 ,同时初步探讨了聚合膜分别在非水溶液和水溶液中的氧化还原行为及稳定性 ,其中借助EQCM重点讨论了在这些过程中溶液中离子在膜中传输的机理。The electropolymerization of Cobalt tetraaminophthalocyanine(CoTAPc) on gold electrode has been studied by cyclic voltammetry and electrochemical quartz crystal microbalance(EQCM). We studied the effects of various parameters on the polymer growth such as solvents, electrolytes, scan rates, and the CoTAPc concentration etc. The redox characterization and the stability of the conducting film on repeating charging and discharging were checked in aqueous and non-aqueous solutions. Especially, the ion transportion plays an important role in these processes.
