摘要:

使用硅烷偶联剂 3-氨丙基甲基二甲氧基硅烷(3-(dimethoxymethylsilyl)propylamine) 和不同氧化程度的氧化石墨烯(graphene oxide, GO)在玻片表面采用浸渍法制备了一种在水环境下具有较好润滑性能的氧化石墨烯涂层. 通过傅里叶变换红外光谱 (Fourier transform infrared spectrometer, FTIR)仪、拉曼光谱(Raman spectra)分析法、水接触角(water contact angle, WCA)测试等方法研究了涂层的表面形貌及其特征. 研究结果表明, 所制备的硅烷/氧化石墨烯涂层表面均一, 没有明显的缺陷. 摩擦测试结果显示, 涂层能够有效提高耐磨性能, 不同氧化程度的氧化石墨烯对抗磨性能有着不同的影响, 氧化程度越高, 抗磨性能越好.

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
