Ac conductivity - temperature dependencies of Au/polyaniline/Au structures with the electrodeposited thin film polyaniline are presented. The data for the reduced and reversibly oxidized polymer samples of estimated thickness being in 10-1-100 žm range are shown. The charge transport laws are found similar to that observed for the chemically prepared conducting polymer. The observed crossover in the conductivity - temperature dependence coincides with the increase in the electrical capacitance of the polyaniline electrode reported earlier.
