▎ 摘　　要

NOVELTY - The layer has copper substrate (1) whose surrounding is covered with anti-oxidation graphene film protection layer (2). The absolute ethyl alcohol and analytically pure acetone are used to clean the copper material. A diluted hydrochloric acid solution with the concentration of 5% is provided to soak the copper material for 5 hours. A graphene film protection layer is provided on the copper surface. The cleaned copper is put into a single region growing furnace. The growth furnace is heated at the temperature of 600 degrees C. USE - Copper anti-oxidation protective layer used in electric, light, mechanical, building, and national defence industries. ADVANTAGE - The copper conductive property can be improved, and the oxidation or corrosion resistance of the copper can be improved. The service life time of the copper material can be prolonged. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for manufacturing copper anti-oxidation protective layer. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the copper anti-oxidation protective layer. Copper substrate (1) Anti-oxidation graphene film protection layer (2)
