NOVELTY - The utility model claims a device for processing surface treatment for graphene piece, comprising vacuum chamber, vacuum pump, air pipe, inflation device, the inflation pipeline, electric control device and at least one electrode pair, at the vacuum chamber set with balance valve, the vacuum pump air suction pipe connected through vacuum chamber, the inflation device by inflation pipe connected to vacuum chamber inside, the electrode set in vacuum chamber inside, and a power control device connected with each. The utility model is new type of device operation is simple and clean time is short, production efficiency high, scale can clean after made graphene, the graphene clean piece made outside surface without residual foreign matter, a follow-up oxidation corrosion metal substrate or electrochemical peeling off metal substrate providing earlier stage preparation.
