摘要：

The temperature and potential dependences of the behaviour of poly(aniline) modified electrodes were studied by impedance spectroscopy. It was rendered probable that the ohmic resistance, which can be determined by impedance measurements is in connection with ionic conductivity and practically no information of the electronic conductivity of the polymer can be obtained. No temperature dependence of the low-frequency limiting capacitance was found. The high-frequency capacitance which can be assigned to double-layer at the polymer/electrolyte interface depends strongly on temperature. Both capacitances show cpe behaviour.
