In this study, the nanocomposites of MoS₂ nanoparticles (NPs) grown on carbon nanotubes (MoS₂@CNT), graphene (MoS₂@Gr), and fullerene C60 (MoS₂@C60) were synthesized, characterized, and evaluated for potential use as lubricant additives. By using the benefit of the synergistic effect between MoS₂ and carbon nanomaterials (CNMs), these nanocomposites can be well dispersed in polyalkylene glycol (PAG) base oil and show superior stability compared with pure MoS₂ NPs. Moreover, the dispersions of MoS₂@CNT, MoS₂@Gr, and MoS₂@C60 added in PAG have noticeably improved friction reducing and antiwear (AW) behaviors at elevated temperature for comparison with that of PAG and PAG containing CNT, Gr, C60, and MoS₂ NPs, respectively. The enhanced lubricating properties of these nanocomposites were also elucidated by exploring the tribofilm formed on the disc.

在这项研究中，合成，表征和评估了在碳纳米管（MoS ₂ @CNT），石墨烯（MoS ₂ @Gr）和富勒烯C60（MoS ₂ @ C60）上生长的MoS ₂纳米颗粒（NPs）的纳米复合材料。用作润滑剂添加剂。通过利用MoS ₂和碳纳米材料（CNM）之间的协同效应，这些纳米复合材料可以很好地分散在聚亚烷基二醇（PAG）基础油中，并且与纯MoS ₂ NP相比，具有出色的稳定性。此外，MoS ₂ @ CNT，MoS ₂ @Gr和MoS ₂的分散体与分别包含碳纳米管，Gr，C60和MoS ₂ NP的PAG和PAG相比，PAG中添加的@ C60在高温下具有显着改善的减摩和抗磨（AW）行为。通过研究在圆盘上形成的摩擦膜，也阐明了这些纳米复合材料增强的润滑性能。
