摘要
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 in such systems of two characteristic values: radius of the filler particle and radius of charge permeability in the polymer matrix. This assertion predicts a range of cases, covering the spectrum from a solid-spheres problems to the problem of interpenetrating spheres of percolation theory and was studied by means of a Monte-Carlo computer simulation. Detailed mechanisms, responsible for such pecularities in charge transfer, are also discussed.
