Popis:	Films of poly(3,4-ethylenedioxythiophene) (PEDT) are synthesized during anodic polarization from a water-acetonitrile mixture containing sulfo-cationite MF-4SK and without it. A comparison of electrochemical and spectroelectrochemical characteristics of the films and an elemental analysis evidence the formation of composite PEDT–MF-4SK. The immobilization of the polymer anion in the PEDT matrix is shown to alter its oxidation mechanism. For a neutral composite film, this mechanism includes the exit of sulfo-cationite cations and the entering of supporting anions.
