Object of the research refers to carbon nanomaterials (CNM) and physical and technical processes of their production. Methods of the research comprise mathematical modeling and diagnostics of electrophysical processes. Methods of electrodischarge synthesis of new compositions of carbon nanomaterials with various electrophysical properties are developed in the course of pulse high-energy impacts on graphite, organic fluids and gaseous hydrocarbons. Different quantities of specific electroconductivity of graphite conductors synthesized by al electric explosion from 10 to 120 S/m (at density over 1,000 kg/m) are conditioned by the presence of new allotropic phases of carbon in powders - graphenes, nanotubes, fullerene and diamond-line nanoparticles. It is shown that the measured specific electroconductivity of carbon nanomaterials produced by electrodischarge treatment of various organic fluids is within 0.008 to 200 S/m and depends both on the carbon source and compaction degree. Various quantities of electroconductivity and density are ascribed to various ratios in carbon atom powders in sp2- and sp3- hybrid states. Approximation of dependence between specific electroconductivity and a type of carbon nanomaterial is proposed which allows assessing the share of atoms in the sp2-hybrid state without resort to complex research of synthesized carbon nanomaterials.
