Abstract

Electrochromic thin films of polyaniline were prepared by electropolymerization of aniline from an acidic aqueous solution on platinum and conducting glass surfaces. An in situ FTIR spectroelectrochemical technique was used to investigate structural changes of the film during oxidation and reduction. Coloring (oxidation) and bleaching (reduction) of the film were shown to be associated with the deprotonation and protonation of the film. It was detected that the N—H stretching band around 2970 cm⁻¹ decreased as the film was gradually oxidized.
