摘要：

An attempt has been made to model mathematically the capacitive component of the current obtained in cyclic voltammograms of polymer-coated electrodes. The capacitance data used were obtained by means of electrochemical impedance spectroscopy (EIS) measurements performed in situ during the potential sweeps. It was shown that the capacitive current flowing during the oxidation and reduction processes strongly depends on both the low frequency capacitance of the polymer and its changes during the sweep.
