Abstract

The ionic conductivity of the film of poly( p -diethynylbenzene- co -propargylalcohol) (DEB- co -OHP) doped with iron trichloride has been investigated in the temperature range 25–60°C at a fixed value of the relative humidity (RH) (100%). Both the film conductance and capacitance have been found to be dependent on temperature. An equation valid for ion solutions, the Onsager-modified equation, has been satisfactorily used to describe the conductance trend with temperature.

Abstract

The change in the electrical properties were investigated as a function of relative humidity by several techniques (among them the electrochemical impedance) for different ion-conducting polymers, sprayed as films on interdigitated gold electrodes. It was found that the equations valid for electrolytic solutions fit the experimental data. In particular, the Onsager equation, applied to the relevant parameters of the polymeric films, describes the change in the film resistance as a function of relative humidity satisfactorily.
