NOVELTY - Preparing aqueous graphene coating involves measuring 30 ml concentrated sulfuric acid by using a measuring cylinder, adding concentrated sulfuric acid into a 250 ml beaker, weighing 2 g graphite by using an electronic balance, adding graphite into the same beaker, putting the beaker into an electromagnetic stirrer, and slowly stirring until the concentrated sulfuric acid and the graphite are uniformly mixed. A proper amount of fuming nitric acid is slowly added into the solution under stirring for reaction, and then filtered the solution by using deionized water to obtain graphite oxide. The graphite oxide is added into 250 ml beaker with 60 ml concentrated sulfuric acid under stirring in an ice bath. 3 g potassium permanganate is slowly added into the obtained solution under stirring the continuously, and added the solution into deionized water. 15 ml hydrogen peroxide is added into the obtained solution, and then filtered, washed by using hydrochloric acid and deionized water. USE - Method for preparing aqueous graphene coating with moisture-proof and antistatic properties. ADVANTAGE - The method prepares the aqueous graphene coating with moisture-proof and antistatic properties in a simple, cost-effective and eco-friendly manner with strong oxidizing property of potassium permanganate, moisture-proof and antistatic performances by using sodium allylsulfonate as a polymerizable emulsifier and using multiple organic solvents such as methyl methacrylate, butyl acrylate and aniline monomers as raw materials. DETAILED DESCRIPTION - Preparing aqueous graphene coating involves measuring 30 ml concentrated sulfuric acid by using a measuring cylinder, adding concentrated sulfuric acid into a 250 ml beaker, weighing 2 g graphite by using an electronic balance, adding graphite into the same beaker, putting the beaker into an electromagnetic stirrer, and slowly stirring until the concentrated sulfuric acid and the graphite are uniformly mixed. A proper amount of fuming nitric acid is slowly added into the solution under stirring for reaction, and then filtered the solution by using deionized water to obtain graphite oxide. The graphite oxide is added into 250 ml beaker with 60 ml concentrated sulfuric acid under stirring in an ice bath. 3 g potassium permanganate is slowly added into the obtained solution under stirring the continuously, and added the solution into deionized water. 15 ml hydrogen peroxide is added into the obtained solution, and then filtered, washed by using hydrochloric acid and deionized water, taken out the filter paper by using tweezers after the residual solid is stabilized on the filter paper. The graphene oxide is added into 200 ml dehydrated N, N-dimethylformamide solvent in a 500 ml three-neck flask, and freeze-dried. 1 mg resorcinol, 30 mg triethylamine, 30 mL acrylic acid are added into the uniformly dispersed graphene oxide, placed into flask into an electromagnetic stirrer under stirring with 30 mL thionyl chloride in an ice bath. The obtained solution is filtered to remove the insoluble matter to get brown product. The solution is centrifuged in a centrifuge device to remove a small amount of self-polymerized acrylic acid and by-products, freeze-dried the precipitate to obtain a brown product modified graphene oxide, and then added modified graphene oxide and an appropriate amount of sodium allyl sulfonate, and deionized water into a 250 ml three-necked flask in a nitrogen atmosphere. An appropriate amount of potassium persulfate solution is added under stirring, where the remaining potassium persulfate initiator solution, butyl acrylate blending monomer, methyl methacrylate, sodium allyl sulfonate and modified graphene mixed solution are dropped uniformly. 1 g dodecylbenzene sulfonic acid, 0.2 g ammonium persulfate and 30 mg p-phenylenediamine are added to the solution under stirring in an ice bath. 0.1 g aniline monomer is added to 100 ml deionized water under stirring in an ice bath, and then poured the solution into the solution under ice bath conditions. The obtained solution is washed with deionized water, ethanol, and xylene, and filtered to obtain the water-based graphene coating.
