Abstract
Abstract Polystyrene (PS) composite films, containing various fractions of each of NiCl2, CoCl2 and mixtures with Ni or Co powder, were prepared by casting method. The samples were investigated by optical and scanning electron microscopes and differential scanning calorimeter. The temperature dependence of the dc electrical resistivity was interpreted on the basis of the polaron hopping model. The hopping energy states were assumed to be arised from the previously calculated 6-fold symmetric potential barrier due to the phenyl ring rotation. The polaron band width was calculated and its dependence on the filler content was explained.
