▎ 摘  要

NOVELTY - Producing graphene-metal composite wire, comprises (1) growing graphene on a surface of an original metal wire by means of a chemical vapor deposition process; (2) performing a composite twisting process on the obtained wire; (3) performing a pre-tensioning and pre-straining process on the obtained wire; (4) performing a cold drawing process on the obtained wire; and (5) performing a chemical vapor deposition process on the obtained wire, the wire passing from step (2) through step (5) sequentially in a cycle to be repeated n times, where f wires obtained in step (1) are selected for a first cycle, f wires obtained from the previous cycle are selected for each of all subsequent cycles, and finally a graphene-metal composite wire equivalent to f n strands is obtained, where f is integer from 2-9, and n is integer of greater than or equal to 6. USE - The method is useful for producing graphene-metal composite wire.
