The morphology of additives has strong effects on the tribological performance of lubricant. In this work, molybdenum disulfide (MoS₂) nanowires (NWs) prepared by electrospinning method are used as an additive in perfluoropolyether (PFPE) base oil for the first time. The influence of MoS₂ NWs on the tribological properties of PFPE oil is evaluated using a four-ball tester. The results show that PFPE oil containing 1.0 wt% MoS₂ NWs exhibits significant improvements in reducing friction and anti-wear properties with the minimal friction coefficient (0.11) and wear scar diameter (452 μm) under high vacuum due to the unique NW morphology and good dispersion of MoS₂ NWs in PFPE.

添加剂的形态对润滑剂的摩擦学性能有很大的影响。在这项工作中，通过静电纺丝法制备的二硫化钼（MoS ₂）纳米线（NWs）首次用作全氟聚醚（PFPE）基础油中的添加剂。使用四球测试仪评估MoS ₂ NWs对PFPE油的摩擦学性能的影响。结果表明，由于独特的NW形貌和化学性质，含有1.0 wt％MoS ₂ NWs的PFPE油在降低摩擦和抗磨性能方面具有显着改善，在高真空下具有最小的摩擦系数（0.11）和磨损痕迹直径（452μm）。 MoS ₂ NW在PFPE中的良好分散。
