Abstract

Abstract: The method of producing low-density carbon materials by thermal destruction of grinded graphite foil saturated with aqueous solutions of: 1) ammonium nitrate, 2) carbamide, or 3) surfactant was developed. The electrophysical properties of low-density carbon materials and expanded vermiculite/low-density carbon material composites were investigated. Percolation thresholds for electrical conductivity for studied systems were determined. Critical exponents in classic theory electrical conductivity were calculated
