Abstract

Electrochemcial properties of evaporated amorphous films on conductive glass substrates have been studied in organic electrolytes in order to clarify the influence of water in the films on electrochromism. Compositions of water in the film have been analyzed by using FT‐IR spectra and 1H‐NMR. We conclude that the water adsorbed in the film during the evaporation and from ambient air not only leads to a fast electrochromic reaction at first, but also reacts gradually with by hydroxylation and/or hydrolysis to shift the potential of the cathodic reaction to the negative side and that the hydroxylated film layer loses the electrochromic coloration density.
