NOVELTY - Preparation of micro-arc oxidation film-zeolitic imidazolate framework-8-graphene oxide/layered double hydroxides film on surface of magnesium alloy comprises carrying out micro-arc oxidation to surface of magnesium alloy to form film, putting magnesium alloy after micro-arc oxidation into graphene oxide growth liquid solution for in-situ growth, reacting at 125-145 degrees C with pH value of 9-12.5 for 10-20 hours, putting in mixed solution of dimethylimidazole and zinc nitrate hexahydrate to grow in situ, reacting at room temperature for 5-35 hours, ultrasonically cleaning magnesium alloy after reaction, using deionized water to wash, and drying to obtain product. USE - The method is used for preparing micro-arc oxidation film-zeolitic imidazolate framework-8-graphene oxide/layered double hydroxides film on surface of magnesium alloy for aviation, automobile, and electronic communication (claimed). ADVANTAGE - The method enables to prepare magnesium alloy surface micro-arc oxidation film-8-graphene oxide/ZIF composite film in a simple and eco-friendly manner.
