| Popis: | In this research, the effect of ProDOT (3,4-propylenedioxythiophene) monomer on the electrochromic properties of dithienylpyrrole type copolymer has been studied. The copolymers of these two components have obtained by electroanalytical methods in different monomer ratios. The morphological, optical and electrochemical characterizations of all copolymers were investigated. The electrochromic properties of the novel films were investigated by cyclic voltammetry and spectroelectrochemical methods. Different colors of the electrochromic films were achieved under different applied potentials. The maximum difference of the UV–vis absorption of the film was found about 42% between − 0.6 V and 1.2 V at 850 nm for P(C3) copolymer with a fast switching time (0.4 s). The morphological and chemical analyses for copolymers were also detected. |
