Vinyl ester resins (VERs) are often used as anti-corrosive coating due to their high curing speed and good me-chanical property in most industrial fields. However, many small holes can be formed during the curing process of these resins, resulting in they are not suitable for heavy anti-corrosion applications. Herein, approximately 100% utilization rate of raw materials and solvent-free polyfunctional acrylates (AGO-VERs) with excellent anti-corrosive properties are synthesized by crosslinking VERs with silane decorated graphene oxide (AGO) using toluene diisocyanate as the crosslinking agent. Compared with GO-VERs, AGO-VERs show better dispersibility and higher degree of peeling in the resin systems. Furthermore, the cured coating containing AGO-VER-6 exhibits the maximum tensile strength (80.73 MPa), flexural strength (178.58 MPa), Young's modulus (669.53 MPa) and impedance modulus (2.43 x 10(8) omega cm(2) after soaking for 7 d). Finally, the possible corrosion protection mech-anism of the modified VERs is clarified. Results demonstrate a simple and efficient approach for covalently combining VERs with GO well, which can achieve long-term corrosion protection of metal substrates in the field of heavy anti-corrosive coatings.
