Abstract :
We have obtained impedance measurements of PEDOT:PSS films and propose a novel interpretation for electrical charge transport mechanisms in the polymer. A parabolic subdiffusion model produced excellent fitting for the impedance data, suggesting that anomalous ion diffusion limits charge transfer through the nanoporous film.
