本文研究了三种可溶性聚酰亚胺（ＰＩ）在有机溶剂和水溶液中的电化学行为，发现ＰＩ在有机溶剂中的电化学行为明显不同于水溶液．利用红外光谱技术和半经验分子轨道计算方法，结合电化学测试的结果，确证了ＰＩ的电化学反应的机理．
In this paper, the electrochemical behavior of three soluble polyimides (PI) in organic solvents and aqueous solutions was investigated. The electrochemical behavior of PI in organic solvents was found to be significantly different from that of aqueous solutions. Using infrared spectroscopy and semi-empirical molecular orbital calculation method, combined with the results of electrochemical tests confirmed the electrochemical reaction mechanism of PI.
