I n this paper, MoS2 ultrathin nanosheets with high purity were successfully synthesized via a facile hydrothermal method. T he microstructure and morphology of as-prepared MoS2 were characterized by High solution transmission electron microscopy (HRTEM) , X-ray powder diffraction (XRD) , and Raman spectrum (RS) . W hen evaluated as a lubricating additive for polyimide composites, the results of friction and wear test showed that PI-MoS2 composites exh ibited outstanding friction-reducing and anti-wear properties . In particular,when the MoS2 content wa s 7wt.%., the friction coefficient and wear rate of corresponding composite decreased 29% and 88%, respectively. More importantly, the PI-7wt.% MoS2 composite still possessed low friction coefficient and wear rate under high load or sliding rate. T his implied that MoS2 ultrathin nanosheets owned excellent self-lubricating property, and was a promising lubricating additive to enhance the tribological p roperties of polymer
