▎ 摘　　要

In the current paper, trilayered films (abridged as APS-GO/PFPE) composed of graphene oxide (GO) and perfluoropolyethers (PFPE) were fabricated successfully on the silicon substrate pre-modified with a self-assembled monolayer of 3-aminopropyl triethoxysilane. The so-prepared films were characterized by a range of complementary techniques including Raman spectroscopy, contact angle measurements, X-ray photoelectron spectroscopy, and atomic force microscopy, to reveal the surface chemical compositions and surface morphologies. Furthermore, the microtribological behavior of the so-prepared films was studied on a ball-on-plate tribometer. The APS-GO/PFPE film showed better friction-reducing and wear-resisting properties as compared with the control samples, which was ascribed to the excellent wear-resisting properties of GO and the excellent lubricating nature and low shear strength of PFPE.
