Dynamic Monte-Carlo simulation of electrochemical switching of a conducting polymer film

Dynamic Monte-Carlo simulations of insulating/conducting transition of an electrochemically deposited conductive polymer film have shown that the peak potential of linear sweep voltammetry could be considered as a first approximation of the percolation threshold potential of the deposited film. In order to verify this, the insulating/conducting transition of the electrochemically deposited poly-ortho-aminophenol (POAP) films was studied by chronoamperometry. The propagating conductive clusters in the film were found to percolate at the threshold potential in the range of 0.15–0.17 V/Ag, AgCl, near the peak potential of the corresponding cyclic voltammogram.
