▎ 摘　　要

NOVELTY - The method comprises forming graphene in a polymer layer surface and then irradiating, and coating a carbon source polymer on a metal wire or a board by spin coating, dip-coating or spray coating. The irradiating step is carried out at a frequency of 1-10 GHz. The method further comprises heating polymer layer at a temperature of 1500 degrees C. USE - The method is useful for manufacturing a metal wire (claimed). ADVANTAGE - The method is capable of simply and economically manufacturing the metal wire with excellent electric conductance and thermal conductance and improved electrical and thermal characteristics. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a method for manufacturing a metal wire.
