Electrical properties of organic semiconductors based on polyacrylonitrile
Abstract
Conductivity and static permittivity of heat-treated polyacrylonitrile products with polyconjugation regions are measured in the vicinity of the percolation threshold. It is found that below this threshold, the experimentally obtained dependences of conductivity and static permittivity on the volume content of polyconjugation regions in these materials differ from the dependences calculated within the percolation theory. The origin of this discrepancy is discussed in terms of the spatial-structural hierarchical model proposed by Balberg et al. for composite materials. Analysis of the temperature dependence of conductivity within the local activation energy of conductivity in them shows the formation of a continuous spatial structure of tunnel-connected polyconjugation regions.
