Alternating current (AC) bipolar electropolymerization of 3,4-ethylenedioxythiophene (EDOT) using a gold (Au) wire as a bipolar electrode (BPE) on a substrate surface resulted in gradual growth of the corresponding poly(3,4-ethylenedioxythiophene) (PEDOT) thin film from the terminals of the Au wire on the substrate. Studies to clarify the polymerization behavior were conducted under various electrolytic conditions, including monomer concentration, applied frequency, monomer structure, and substrate material. This method could be used to draw conducting polymer films on a nonconductive substrate, guided by an applied external electric field, and thus has potential for circuit patterning in organic electronic devices.
