Abstract
The heavy anticorrosive coating industry demands coatings with exceptional mechanical properties and corrosion resistance to withstand the challenges of severe corrosion environments. Incorporating graphene with barrier function into vinyl ester resins (VER) to achieve above-mentioned performances enhancements has garnered considerable attention. Herein, a novel solvent-free, nearly 100 % raw materials utilization polyfunctional acrylate (SMAGO-VER) has been developed by using styrene-maleic anhydride copolymer and GO covalent cross-linked hybrid (SMAGO) and acrylic coring-opening epoxy resin. SMAGO exhibited well stability and dispersibility in the resin system. The composite coating containing SMAGO-VER showed enhanced mechanical properties, thermal stability and corrosion resistance due to the synergistic effect of copolymer and GO. The mechanism of enhancement was elucidated through various evaluation methods such as electrochemistry and equivalent circuit model. To conclude, this approach provides an effective strategy to address the limitations of traditional VER materials for better application in the field of heavy anticorrosive coatings.
