▎ 摘　　要

NOVELTY - Method for preparing a highly conductive copper wire coated on a graphene surface, involves taking a graphene quantum dot solution, taking copper wire, arranging graphene quantum dots on the surface of the copper wire, and annealing the copper wire with the graphene quantum dots on the surface in a protective atmosphere to obtain the highly conductive copper wire coated on the graphene surface. USE - The method is used for preparing high conductive copper wire coated on graphene surface for electricity transmission and electricity utilization in academic and industrial sectors. ADVANTAGE - The method enables to prepare high conductive copper wire coated by graphene surface, which reduces the energy waste and makes the industrialization possible. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a high-conductivity copper wire coated on the surface of graphene comprising copper wire and graphene coated on the surface of the copper wire.
