摘　　要：吡咯在乙二醇/乙睛混合溶剂中以对甲苯磺酸四乙基胺为支持电解质,在恒电流或恒电位条件下进行在镍电极上的电化学氧化聚合。元素分析及红外光谱表明有少量乙二醇参加了反应。扫描电镜图表明,在其接触镍电极的一面呈纤维状堆积,与在铂电极上的形态不同。电导率为10s/cm数量级。热失重分析表明,氧化态的聚吡咯膜在300℃以下是稳定的。Pyrrole(PY) was electrochemically polymerized on Ni electrode by using Et4N(TsO) as electrolyte in ethyleneglycol/acetonitrile solvent with constant current or constant voltage. The electrical conductivity is around 10 s/cm. TGA results show that the film is stable under 300℃. Results of elemental analysis, FTIR, SEM are also reported.
