Abstract A novel hybrid of 2D/2D h-BN/MoS2 was fabricated via facile in-situ hydrothermal method. The chemical composition and microstructure of as-prepared h-BN/MoS2 hybrid were determined, and its enhancement on the tribological properties of epoxy (EP) coating was investigated systematically. Results showed that MoS2 nanosheets were homogeneously and perpendicularly decorated on the hydroxylated h-BN (h-BN-OH) surface, which avoided the agglomeration of MoS2 nanosheets and endowed h-BN with much rougher surface and chemical activity. Furthermore, the h-BN/MoS2 hybrid reinforced epoxy composite coating showed the optimal anti-friction and wear-resistance. The friction coefficient and wear rate of EP composite coating were decreased by about 80% and 88% by the incorporation of h-BN/MoS2, and the composite coating still kept excellent tribological properties under harsh sliding conditions, as a result of the good dispersion of MoS2, high activity of h-BN, synergistic enhancing effect of h-BN/MoS2, as well as the formation of transfer film on the sliding surface.

二维/二维 h-BN/MoS2 杂化增强环氧基自润滑复合涂层的摩擦学性能

摘要 通过简便的原位水热法制备了一种新型的二维/二维 h-BN/MoS2 混合物。确定了所制备的 h-BN/MoS2 杂化物的化学成分和微观结构，并系统地研究了其对环氧 (EP) 涂层摩擦学性能的增强。结果表明，MoS2纳米片在羟基化的h-BN（h-BN-OH）表面上均匀垂直地装饰，避免了MoS2纳米片的团聚，并赋予h-BN更粗糙的表面和化学活性。此外，h-BN/MoS2 杂化增强环氧树脂复合涂层表现出最佳的抗摩擦和耐磨性。h-BN/MoS2的掺入使EP复合涂层的摩擦系数和磨损率降低了约80%和88%，
