▎ 摘　　要

NOVELTY - A tin-graphene composite plating film (4) comprises a base material for electric connection and an tin-graphene composite plated on the surface of the base material. The size of graphene (2) is 0.01-6 μ m and content of graphene (2) is 0.5-30 atomic%. USE - Tin-graphene composite plating film is used for vehicle-mounted terminal for electric vehicles and plug-in hybrid vehicles, electronic component of various electronic devices and connector for automobile. ADVANTAGE - The tin-graphene composite plated film component has high conductivity, wear resistance, heat resistance, abrasion resistance and durability, and is economical. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of tin-graphene composite plated film on the surface of copper.
