▎ 摘  要

NOVELTY - Industrial-scale production of graphene from carbon black, used as a raw material for obtaining self-assembling nanotubes, involves manually subjecting carbon black (amorphous carbon) (C) under pressure in high temperature reactor; heating and cooling to complete 1-50 cycles; allowing total cycles to cool to room temperature for 1-74 minutes until it acquires a range close to room temperature; carrying out inverse cycle, freezing, and heating material inside reactor under same conditions of 1st cycles; and once reverse cycle is finished, letting it stand at room temperature, for 24-2 hours. USE - The method is useful for industrial-scale production of graphene from carbon black, used as raw material for obtaining self-assembling nanotubes (claimed), used as raw material in batteries, conventional electric circuits, used in compressible and non-compressible electromagnetic systems, and used in chemical industry. ADVANTAGE - Industrial-scale production of high quality graphene is provided.
