A novel hybrid material composed of micro-carbon fiber (CF) and hexagonal MoS₂ nanosheets was prepared via a one-step hydrothermal method. The hybrid simultaneously had both lubricating and reinforcing effects to improve friction and wear properties of polyimide (PI). More importantly, MoS₂ nanosheets decorated onto the surface of CF increased the interfacial adhesion between CF and the PI matrix. This enhanced the hardness and thermal stability, and was also favorable for transferring stress from the matrix to CF during friction and wear process. Accordingly, the PI/CF-MoS₂ composite exhibited outstanding tribological properties. Also, its friction coefficient and wear rate were only 0.24 and 2.01 × 10⁻⁶ mm³/N m, respectively, which were lower than those of PI, PI/CF and PI/MoS₂; this suggested CF-MoS₂ hybrid was a promising additive for enhancing the tribological properties of polymers.

通过一步水热法制备了由微碳纤维（CF）和六角形的MoS ₂纳米片组成的新型杂化材料。该杂化物同时具有润滑和增强作用，以改善聚酰亚胺（PI）的摩擦和磨损性能。更重要的是，装饰在CF表面的MoS ₂纳米片增加了CF与PI基质之间的界面粘附力。这提高了硬度和热稳定性，并且还有利于在摩擦和磨损过程中将应力从基体传递到CF。因此，PI / CF-MoS ₂复合材料表现出优异的摩擦学性能。此外，其摩擦系数和磨损率仅为0.24和2.01×10 ^-6  mm ³/ N m分别低于PI，PI / CF和PI / MoS _2的/ N m ；这表明CF-MoS ₂杂化物是增强聚合物摩擦学性能的有前途的添加剂。
