The study focuses on the carbon nanomaterials (CNM) and physicotechnical processes of their production. The purpose of the study is to determine the energy and thermodynamic conditions, mechanisms, and regularities of the synthesis of various carbon nanostructures, phase composition, structural state, and also electrophysical properties of CNM produced as a result of structural and phase transitions of carbon during the high-energy pulse processes of an electrical explosion of graphite conductors or plasmochemical reactions occurring during the discharge-pulse treatment of liquid and gaseous hydrocarbons with different degrees of hydrogen atom hybridization. The methods of the study include mathematical modelling and diagnostics of electrophysical processes. Proceeding from the theory of interaction of a powerful electrodischarge current pulse and the condensed substance the energy and thermodynamic conditions of structural and phase transitions of carbon resulting in a synthesis of various carbon nanostructures are determined. For the first time the analytical expressions are obtained allowing to calculate the electrophysical properties responsible for the evolution of a substance state, which allows us to govern the process of an electroexplosion of graphite conductors. The test-bed assembly is produced for the discharge-pulse treatment of graphite, liquid and gaseous hydrocarbons with pulse repetition frequency from 1 to 10 kHz. Electroexplosive processes are explored at high velocities of current rise, and also the thermodynamic conditions of various carbon nanomaterials production. Phase routes of carbon for different modes of an electroexplosion are constructed. As a result of the electrodischarge treatment of liquid and gaseous hydrocarbons the amorphous carbon, carbon nanotubes, fibers and films are produced.
