ANALYSIS OF PECULIARITIES IN PERCOLATION BEHAVIOR OF SOME CONDUCTING POLYMER COMPOSITES

The differences of conductivity behavior of polymer composite systems observed by us from that predicted by percolation theory are described , from our point of view, by a simple model predicting the existence i n such systems of two characteristic values: radius of the filler part icle and radius of charge permeability in the polymer matrix. This ass ertion predicts a range of cases, covering the spectrum from a solid-s pheres problems to the problem of interpenetrating spheres of percolat ion theory and was studied by means of a Monte-Carlo computer simulati on. Detailed mechanisms, responsible for such pecularities in charge t ransfer, are also discussed.
