Abstract Hexagonal boron nitride (h-BN), a structural analogue of graphene, is a better alternative for anticorrosive coatings because of its electrical insulation properties. In this work, few-layer h-BN nanosheets are obtained by the exfoliation of stacked h-BN powders with poly(2-butyl aniline) (PBA) and incorporated into epoxy coatings for protecting metallic substrate against corrosion. Results show that as prepared composite coatings exhibit high impedance modulus and low water absorption, suggesting their superior performance of corrosion protection owing to the “labyrinth effect” of h-BN and passivation effect of PBA on the metal substrates.

用于环氧涂层协同防腐增强的可加工聚（2-丁基苯胺）/六方氮化硼纳米杂化物

摘要 六方氮化硼 (h-BN) 是石墨烯的一种结构类似物，由于其电绝缘性能，是防腐涂层的更好替代品。在这项工作中，通过用聚（2-丁基苯胺）（PBA）剥离堆叠的 h-BN 粉末并结合到环氧树脂涂层中以保护金属基材免受腐蚀，获得了几层 h-BN 纳米片。结果表明，制备的复合涂层表现出高阻抗模量和低吸水率，表明由于 h-BN 的“迷宫效应”和 PBA 对金属基材的钝化作用，它们具有优异的防腐性能。
