ABSTRACT
93Polymers of polyaniline series (namely, polyaminoarenes) are considered as the perspective materials for electrochromic devices from the point of view of physical chemistry of electrooptic phenomena. The main regularities of polyaminoarenes films formation on transparent semi-conducting surfaces have been studied based on the results of electrochemical, optical, and spectroelectrochemical investigations. The relationship between the electrochemical and also electrooptical characteristics and the structure of polymers was established. On a basis of determined diffusion coefficients and heterogeneous constants of a charge transport in different electrolytic media it was shown, that the structure of a polymeric chain has the decisive effect on the electrochromic material efficiency. Some possible methods of electrochromic characteristics improvement for polyaniline (PAn) and its derivatives have been proposed.
