STRUCTURE EFFECTS ON CONDUCTIVITY OF ELECTRICAL CONDUCTING POLYMER COMPOSITES. A REVIEW

The role of the content of conducting filler and structural peculiarities of electrical conducting polymer composites has been considered. Different conceptions on the nature of the conductivity and the mechanisms of charge transfer in heterogeneous structures are presented in this review. Experimental results obtained by different scientists only partially are in concordance with the existing theoretical models. It is suggested that missing of various physical and chemical factors influencing the processes of electrical Current formation in polymer composites is one of the main reasons of the mentioned divergence between theory and experimental results among which the rate of the values of inter- and intra-phase interactions ill composites may be considered as a very important factor. The peculiarities of dependence of the conductivity of systems with binary conducting fillers on the fillers content are considered in this work, too.
