摘要: We present a comprehensive study of the transport properties in polyaniline-Nafion and polyaniline-polyethylene oxide, lithium trifluoromethane sulfonimide complex blends, together with careful characterization morphology polyaniline protonation level. They include conductivity measurements as function both content blends temperature for given composition. show that percolation theory can account data provided hopping tunneling are taken into account. Moreover, variation level blend composition appears crucial parameter. The leading conduction mechanism is shown to be process between highly conducting grains, parameters which determined by composition,
