Thick poly(3,4-ethylenedioxythiophene) films incorporating various anion dopants were anodically deposited from aqueous solutions. In situ AC conductometry was applied during the electropolymerisation and the conductivity Values obtained in different electrolyte systems were compared. The results indicate that 3,4-ethyienedioxythiophene can be polymerised also from relatively dilute aqueous solutions containing various types of electrolytes and that the most conducting films are obtained using large organic anions.
