▎ 摘　　要

NOVELTY - A graphene coated silver alloy wire is provided. The composite wire includes a core wire and one to three layers of graphene covering surfaces of the core wire. The core wire is made of a silver-based alloy including 2 to 6 weight percent of palladium or further added with 0.01 to 10 weight percent of gold. The invention also includes a manufacturing method immersing the core wire into a solution including graphene oxide and applying bias to the core wire for manufacturing the graphene coated silver alloy wire.
