NOVELTY - The preparation method of coating involves dispersing graphene oxide in distilled water, adding sodium 1-naphthalenesulfonate and hydrazine hydrate and then performing reduction reaction, centrifuging the mixture and then washing, grinding the mixture, adding hydroxylated multi-walled carbon nanotube, surfactant, anhydrous ethanol, concentrated nitric acid and carbon fiber and then cutting, adding mixed diluent, epoxy resin, defoamer and curing agent and leaving. USE - The method is useful for preparation of coating. ADVANTAGE - The method enables preparation of coating with excellent corrosion resistance.
