Abstract

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 semiempirical molecular orbital calculation and combining the results of the electrochemical measurements, the mechanisms of the electrochemical reactions of polyimides were demonstrated.
