Title:
METHOD FOR MANUFACTURING GRAPHENE-METAL COMPOSITE WIRE
Document Type and Number:
WIPO Patent Application WO/2020/020153
Kind Code:
A1
Abstract:
A method for manufacturing a graphene-metal composite wire, the method comprising: (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, wherein 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 an integer from 2 to 9, and n is an integer of 6 or more.
