▎ 摘　　要

NOVELTY - The method comprises (i) uniformly mixing copper powder and organic carbon source to prepare composite precursor powder, (ii) putting into copper pipe, sealing two ends of the copper pipe with metal plug, (iii) performing plastic processing to obtain composite wire, and (iv) performing heat treatment to the composite wire to obtain the copper/graphene composite wire. USE - Preparation method of copper/graphene composite wire used in electrical engineering material and energy related field. ADVANTAGE - The preparation method of copper/graphene composite wire is simple and easy to carry out and easy for mass production, and in preparation process, the graphene is in-situ endogenous by copper matrix, with high quality, good dispersibility, strong interface bonding with the matrix, which is good for improving the comprehensive performance of the wire, and has good application prospect in the field of electrical engineering material and the energy related field.
