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．
For the first time, the electrochemical behaviors of the three soluble polyimides were studied in the organic and aqueous solutions. It was found that the electrochemical behaviors of PI in the organic solutions are significantly different from that in the aqueous solution. Using the IR spectroscopy and semiempirical molecular orbital calculation and combining the results of the electrochemical measurements, the mechanisms of the electrochemical reactions of polyimides were demonstrated.
