How is the galvanstatic polymerization of EDOT is done?

I use Na2ClO4 as the surfactant with monomer EDOT. Galvanstatic polymerization of EDOT is required for controlled thickness of the film.

Why use you taking Na2ClO4 as medium of surfactant. Wrong choice. Or any specific reason. You can take DBSA, or Na Laurul sulfate, or Poly styrene sulphonic acid as medium and by taking ratio of EDOT : DBSA :: 0.1: 0.3, electrochemical polymerization can be carried out at a potential of 0.9 V to 1.0 V depending upon which reference electrode you are taking. Take Ag/Ag+ reference electrode. However controlled thickness of PEDOT can be obtained by cyclic voltammetry by cycling the potential between -0.2 V to 1.0 V at a scan rate of 20 mV/sec.
