Relaxation and charge transport phenomena in polyaniline nanofibers: Swift heavy ion irradiation effects

► Non-Debye type relaxation in PAni nanofibers ► Relaxation mechanism dominated by hopping of trapped charges ► Benzenoid to quinoid transition in PAni nanofibers upon SHI irradiation ► Increase in relaxation times upon SHI irradiation ► Charge transport mechanism follows correlated barrier hopping (CBH) model.
