Electrosynthesises and characterizations of copolymers based on pyrrole and 3,4-ethylenedioxythiophene in aqueous micellar solution

► We prepared copolymers based on pyrrole and EDOT in aqueous micellar solution. ► The onset oxidation potential of pyrrole increases with the concentrations of pyrrole decrease in aqueous micellar solution. ► The feed ratio of pyrrole/EDOT plays an important role on the electrochromic properties of the copolymers. ► The incorporation of EDOT units into the Poly(pyrrole) chain improves the electrochemical stability of copolymers.
