Abstract In order to control the preparation of graphene and molybdenum disulfide lubricating oil nanoadditives and further improve their wide-temperature-range lubrication performance, graphene loaded molybdenum disulfide (RGO/MoS₂) nanoparticles were prepared via a one-step freeze-drying method. The microstructure and morphology of the nanoparticles were observed by means of scanning electron microscopy (SEM) and X-ray diffractometry (XRD). The correlation between process parameters and the microstructure of RGO/MoS₂ was explored through ortho-gonal experiments, and the anti-friction and anti-wear performance of RGO/MoS₂ at different temperatures was studied. The results showed that the nanoflower-like spherical RGO/MoS₂ nanoparticles prepared by freeze-drying method uniformly adsorbed on the defect positions on the RGO surface with its thin sheets overlapped with each other, hence exhibited excellent dispersion and stability performance. The factors affecting the thickness of MoS₂ layers in RGO/MoS₂ could be sorted as: freezing method ＞ reaction temperature ＞ reaction time ＞ reaction pH value. The optimal preparation conditions determined included:-20 ℃ freezing, reaction temperature 180 ℃, reaction time 24 h, and reaction pH=1. RGO/MoS₂ as a lubricating oil additive has better friction reduction and wear resistance than MoS₂ single agent at high temperatures. The addition of 1.5wt% RGO/MoS₂ as a lubricating oil additive could achieve an average friction coefficient and a wear rate of only 0.062 5 and 2.95×10^-9 cm³/(N·m), respectively, under high temperature conditions of 250 ℃, 54.3% and 74.5% lower than those acquired by MoS₂ single agent.
