The conductivity and static permittivity of heat-treated polyacrylonitrile products with polyconjugation regions were measured in the vicinity of the percolation threshold. It was found that below this threshold, the experimentally obtained dependences of conductivity and static permittivity on the volumetric content of polyconjugation regions in these materials differ from the dependences calculated within the framework of 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 framework of the local activation energy of conductivity in them shows the formation of a continuous spatial structure from tunnel-connected polyconjugation regions.
