摘要: A study of the electrical conductivity polypyrrole-polyoxyphenylene composites (PPy-POP and PPy-POP-MPcTS) prepared by in situ electropolymerization is presented, where MPcTS stands for tetrasulfonated tetrasodium metallophthalocyanine salts used as a second dopand polypyrrole. The studied function temperature range 77≤T≤300 K. dependence total ac conductivity, frequency 102-105 Hz, changes approximately five orders magnitude, showing sub-linear dispersive behaviour. dc gives evidence transport mechanism based on Mott's variable-range hopping model one dimension PPy-POP composite, which shows crossover to three dimensions PPy-POP-MPcTS composites. Using this we were able calculate meaningful values density states, energy distance.
