可溶性聚苯胺电化学过程的拉曼光谱研究

Raman Spectrooscopic Study on The Electrochemmical Behaviours of Soluble Polyanine

用现场拉曼光谱方法跟踪了可溶性聚苯胺(PAn)的电子化学反应过程,考察了电报电位、电解液pH值对拉曼光谱及循环伏安曲线峰位的影响,提出了三对氧化还原峰的反应机制及在不同电位下的结构变化。

In situ Raman spectra of souble PAn were taken to correlate its electrochemical reactions with structural changes.The pHdependence of Raman spectra andCV peak poisitions was observed.The reaction mechanism of three pairs of redox waves and the structures of PAn at various potentials were deduced, based on the spectral changes.
