h-BN decorated with Fe3O4 nanoparticles through mussel-inspired chemistry of dopamine for reinforcing anticorrosion performance of epoxy coatings

A novel hybrid materials Fe3O4 nanoparticles supported by hexagonal boron nitride (h-BN) is successfully prepared via mussel-inspired chemistry of dopamine by hydrothermal synthesis method. The surface modification and microstructure of h-BN-Fe3O4 are characterized by FT-IR, XRD, XPS, SEM and TEM. The nano-Fe3O4 obtain well dispersion supported by h-BN layer platform, and the h-BN-Fe3O4 hybrid materials exhibit a remarkable superiority in enhancing the anticorrosion performance of epoxy coatings. The lamellar structural h-BN and nano-Fe3O4 provide a significant synergistic effect in anticorrosion performance for epoxy composite coatings. In addition, the anticorrosion mechanisms of h-BN-Fe3O4 are tentatively discussed.
