AI Technical Summary
Existing waterborne acrylic coatings have shortcomings in terms of mechanical strength and long-term corrosion resistance, and graphene oxide has poor dispersibility in waterborne resin systems, which limits its application effect.
Modified graphene oxide is used by grafting 2-hydroxyethyl methacrylate onto the surface of graphene oxide. The phosphate groups of the modified graphene oxide form an interfacial protective layer, which enhances the anti-corrosion performance. At the same time, the acrylate double bonds are polymerized with acrylic monomers to achieve uniform dispersion of graphene oxide.
It improves the mechanical and anti-corrosion properties of water-based coatings, solves the problem of graphene oxide agglomeration in water-based resin systems, extends the penetration path of corrosive media in coatings, and enhances long-term anti-corrosion performance.
