Non-conducting polyphenylene oxide electrogeneration on mild steel by different electrochemical methods

Abstract The electrogeneration of non-conducting polyphenylene oxide on mild steel electrodes has been achieved by cyclic voltametry and polarization at constant potential. The effect of monomer concentration and rotating electrode rate were studied. When these parameters were varied, we concluded from the effect of the electric charge efficiency on the electrode passivation that the polymerization process takes place in the diffusion layer, increasing the charge efficiency at high monomer concentrations and low rotation rates.
