▎ 摘 要
NOVELTY - Manufacture of single crystal copper-nickel alloy involves carrying out nickel plating on the surface of a single crystal copper foil, and annealing to obtain a copper (111) single crystal copper foil. USE - Manufacture of single crystal copper-nickel alloy for preparing multilayer monocrystalline graphene (all claimed). ADVANTAGE - The single crystal copper-nickel alloy of high quality is produced by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of multilayer monocrystalline graphene.
