In order to promote the formation of high-quality graphene-based self-lubricating transfer film. The reduced graphene oxide (RGO) deposited with molybdenum disulfide quantum dots (MoS₂QDs) were successfully prepared. The as-prepared MoS₂QDs/RGO hybrid was used for the first time to improve the tribological properties of polymer composites. Compared with the neat bismaleimide (BMI) and RGO filled composites, the MoS₂QDs/RGO/BMI showed the best tribological properties, and the frictional coefficient and volume wear rate could be decreased to 0.15 and 8.9 × 10⁻⁶ mm³/(N·m), respectively. This is mainly due to the MoS₂QDs loaded on the graphene surface are beneficial to prevent the graphene nanosheet stacking, and the introduction of MoS₂QDs can make the self-lubricating transfer film formed more uniform, smooth and robust during the friction process.

以促进高质量石墨烯基自润滑转移膜的形成。成功制备了沉积有二硫化钼量子点（MoS ₂ QD）的还原氧化石墨烯（RGO）。所制备的 MoS ₂ QDs/RGO 杂化物首次用于改善聚合物复合材料的摩擦学性能。与纯双马来酰亚胺（BMI）和RGO填充复合材料相比，MoS ₂ QDs/RGO/BMI表现出最好的摩擦学性能，摩擦系数和体积磨损率可降低至0.15和8.9×10 ^-6 mm ³ /( N·m)，分别。这主要是由于 MoS ₂加载在石墨烯表面的量子点有利于防止石墨烯纳米片的堆积，而MoS ₂量子点的引入可以使摩擦过程中形成的自润滑转移膜更加均匀、光滑和坚固。
