Abstract: Charge transport in polypyrrole doped with indigo-carmine was investigated by the method of electrochemical alternating current impedance.By the nonllnear least square fitting, the equivalent circuit and parameter of each component are obtained.The apparent diffusion coefficients and heterogeneous electron transfer constants are given.It is found that, along with the increasing of film thickness, Dapp and ko increase also.
