For the first time, nanosized molybdenum disulfide (MoS2) nanoparticles (NPs) were grown on the surface of poly(ethylene glycol)-polydopamine-modified reduction graphene oxide) nanosheets (rGO-PDA-PEG). The obtained rGO-PDA-PEG@MoS2 nanocomposites exhibits excellent dispersion in polyalkylene glycol (PAG) synthetic oil and outperforms GO and MoS2 NPs as additives in terms of friction reduction and wear resistance at elevated temperature. The superior tribological behaviour of rGO-PDA-PEG@MoS2 might be beneficial to the synergistic effect between MoS2 and rGO.

表面改性碳材料上纳米二硫化钼作为减摩抗磨润滑油添加剂

纳米二硫化钼(MoS 2)纳米粒子(NPs)首次在聚(乙二醇)-聚多巴胺改性还原氧化石墨烯)纳米片(rGO-PDA-PEG)的表面上生长。所获得的rGO-PDA-PEG@MoS 2纳米复合材料在聚亚烷基二醇(PAG)合成油中表现出优异的分散性,并且在降低摩擦和高温下的耐磨性方面优于作为添加剂的GO和MoS 2 NPs。rGO-PDA-PEG@MoS 2优异的摩擦学行为可能有利于MoS 2和rGO之间的协同效应。
