Influence of thermal expansion on the conductivity of polymer conducting composites

The temperature dependence of conductivity in systems that undergo a metal-dielectric phase transition is investigated. A quantitative theory is developed that makes it possible to calculate electrical conductivity as a function of temperature for these systems with allowance made for thermal expansion of a polymer and a filler.Deceased.Tashkent State University.
