The layered 2D hexagonal boron nitride (h-BN) nanosheets (BNNSs) have received significant attention as effective fillers for composite protective coatings in anti-corrosion, anti-oxidation and anti-wear applications. Vapour deposited h-BN mono/multilayers are related classes well-recognized as protective thin films and coatings. This review comprehensively accounts for the research and development of BNNSs in protective coatings. Chemical vapour deposited (CVD) BN thin films and exfoliated BNNSs-incorporated composite polymer coatings are primarily discussed. Inorganic and nanocarbon-based composite coatings are also covered. Future research potentials are presented. •Research updates on vapour-deposited h-BN for anti-corrosion, anti-oxidation and anti-wear coatings are presented.•Applications of h-BN nanosheets incorporated inorganic, nanocarbon and polymer-based coatings are detailed.•Exfoliated h-BN nanosheets incorporated epoxy coatings are highlighted.
