Abstract
The electrochromic responses for two kinds of polypyrrole (PPy) films, PPy/inorganic anion and PPy/polyanion composite films, were studied by electromodulation technique. Analyses of electrical and optical responses show that electrochromic responses in conducting state were nearly the same for the both films, however, those in redox active state were characteristic of the two films. The differences in the responses of the two films seem to arise from the differences of both the morphologies of the films and charge transport properties in the films.
