The experimental system used to measure the temperature dependence of the conductivity of polyaniline samples (PANI) in this paper was based on a method of measuring changes in the polarity of the current which flows through a thin sample, in order to eliminate the adverse effects of parasitic voltage on the measurement results. Based on the measured resistance values we calculated conductivity of the treated plyaniline sample and demonstrated its temperature dependence. All measurements were perfomed an a vacuum.
