Abstract

An anti-friction graphene oxide (GO) coating was prepared on a glass substrate using silane coupling agent 3-(dimethoxymethylsilyl)propylamine and GO with different oxidation degrees using the immersion method. The surface morphology and characteristics of the coating were investigated through Raman spectroscopy, Fourier infrared spectroscopy, and water contact angle tests. The results show that the silane/GO coating can be successfully fabricated, and the surface is uniform with no visible defects. For the tribological test, the coating can significantly improve the anti-friction properties of the substrate. The tribological properties of GO are related to its oxidation degree. The higher the oxidation degree of GO, the better the anti-friction properties.

Key words： graphene oxide (GO); different oxidation degree; silane; coating; tribologicalproperty
