Effect of prolonged electrode potential cycling on the charge transport parameters of poly(o-aminophenol) films. A study employing rotating disc electrode voltammetry and surface resistance

On the basis of surface resistance and rotating disc electrode voltammetry measurements, the decrease of the electron transport rate at poly(o-aminophenol) film electrodes caused by prolonged potential cycling was explained in terms of an increase of the electron hopping distance between the redox sites of the polymer.
