With decreasing temperature, the values of DC decrease due to a reduction in the mobility of the polymer chains. Thus, by approaching the glass transition temperature, the value of the conductivity progressively decreases until the plateau of ’ is not any longer measurable in the frequency window of our instrument. At frequencies lower than the characteristic frequency fEP, the conductivity decreases as a result of electrode polarization effects. At frequencies higher than fE, the experimental time becomes smaller than the hopping time of the charge carriers, and thus the electrical response is dominated by local charge fluctuations corresponding to the sub-diffusion regime.
