▎ 摘 要
NOVELTY - Pretreating graphene growth substrate comprises using copper foil or copper-nickel alloy foil as the base, polishing the base, placing in a tube furnace for annealing, taking annealed substrate of the tube furnace, polishing for second time, placing on heating table for heating and oxidation, and using pretreated substrate for chemical vapor deposition growth of graphene. USE - The method is useful for pretreating graphene growth substrate.
