中文摘要	Nanocompositematerials based on graphene and ionic liquids (ILs) with unique and highly attractive properties have received considerable interest in various research ﬁelds, including biosensors, electrochemical sensors, and so on. Given the excellent mechanical properties and frictional properties of graphene nanosheets, nanocomposite ultrathin ﬁlms composed of graphene nanosheets and ionic liquids (ILs) with excellent lubricating property are expected to possess improved compre- hensive tribological performance. In the current paper, various functionalized graphene IL nanocomposite ultrathin lubrica- tion ﬁlms on Si substrates, on the basis of the good dispersion of graphene nanosheets that were noncovalently functionalized by imidazolium-based ILs in acetone, were successfully prepared by an electrostatic adsorption method and were conﬁrmed by several characterization techniques. Appropriate amounts of functionalized graphene nanosheets uniformly distributed on the substrate surface without overlapping greatly enhanced the load-carrying capacity of the ultrathin lubrication ﬁlms, and the new nanocomposite ﬁlms gave excellent micro/nanotribological properties. The novel nanocomposite ﬁlms are hoped to ﬁnd promising applications in the lubrication ofmicro/nanoelectromechanical systems (MEMS/ NEMS).
