Advanced Bio‐Based UV‐Curable Anticorrosive Coatings Reinforced by hBN

Abstract Here, furfuryl methacrylate (FAM) was first successfully synthesized. Bulk hexagonal boron nitride (hBN) nanosheets were exfoliated and dispersed in FAM based on the strong π‐π interaction between hBN and FAM. The few‐layer hBN nanosheets as‐prepared possessed an average thickness of ∼3 nm (less than 10 layers) and exhibited superior storage stabilization under environment condition in FAM. Moreover, we creatively applied FAM solutions containing 0.25‐0.75 wt% of hBN as reactive diluents for the epoxidized soybean oil methacrylate (ESOM) matrix to effectively enhance its corrosion protection by suppressing the penetration of aggressive species. The electrochemical results revealed that the impedance of the coating containing 0.75 wt. % hBN is ∼200 times bigger than that of the blank coating specimen.
