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 degreesC 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.
