Polymerization of 3,4-ethylenedioxy-thiophene (PEDT) was investigated in neutral aqueous solution by electrochemical method. The electrochemical behavior of the polymer, and the electropolymerization mechanism were studied by cyclic voltammetry, FTIR, XPS and UV-spectroscopy. The study of polymerization mechanism showed that the electropolymerization was a radical cation polymerization process, and the anion of some electrolytes which effected the character of the polymer was involved in the polymerization.
