The polyaniline nanocomposite is prepared by dispersing nano zinc oxide in water to obtain nanocarbon material dispersion. USE - Polyaniline-modified coating used in wind power equipment, marine environmental protection, and for long-term preservation of inland diameter onshore steel structures (claimed). ADVANTAGE - The polyaniline-modified coating has high corrosion resistance. DETAILED DESCRIPTION - Polyaniline-modified coating comprises 50-80 pts. wt. graphene, 10-15 pts. wt. polypropylene vinyl acetate, 20-38 pts. wt. epoxy resin, 70-210 pts. wt. zinc powder, 17-40 pts. wt. talc, 10-20 pts. wt. defoamers, 5-8 pts. wt. leveling agents, 5-8 pts. wt. curing agent, 30-70 pts. wt. fillers and 10-15 pts. wt. polyaniline nanocomposites. The polyaniline nanocomposite is prepared by dispersing nano zinc oxide in water to obtain nanocarbon material dispersion. The aniline and p-toluenesulfonic acid are added in nano zinc oxide dispersion at 15-30 degrees C, and an aqueous solution of ammonium persulfate is added and reaction is stirred for 1-24 hours. The obtained product is filtered and filtrate is washed to obtain polyaniline nanocomposite. The ratio of zinc oxide and water is 40-45:100. The ratio of aniline and nano-zinc oxide is 1.1-1.3:1. The molar ratio of toluene sulfonic acid and aniline is 3-7:1. The concentration of p-toluenesulfonic acid is 5-8mol/l. The ratio of ammonium persulfate and aniline is 1.5-1.8:1. The concentration of ammonium persulfate solution is 2-4mol/l. An INDEPENDENT CLAIM is included for a method for preparing polyaniline-modified coating, which involves: (A) mixing zinc dust, graphene nanocomposites and polyaniline at 200-500 revolutions per minute for 30-80 minutes; (B) adding polypropylene, vinyl acetate and epoxy resin, and stirring for 10-15 minutes; (C) adding talc and half amount of defoamer for degassing treatment under vacuum; (D) adding leveling agents, curing agents and filler, stirring at 1000-1200 revolutions per minute, and incubating at 80-90 degrees C for 30-40 minutes; and (E) adding the remaining half of the defoamer and stirring at 1000-1200 revolutions per minute to obtain final product.
