摘要:

采用元素分析、红外光谱(FTIR)、X射线光电子能谱(XPS)、拉曼光谱、X射线衍射(XRD)、固体13C核磁共振波谱(13C MAS NMR)、热失重分析(TGA)、导电率测试以及原子力显微镜(AFM)等手段对正丁基氯化镁还原的氧化石墨烯进行了系统的表征. 结果表明, 正丁基氯化镁可以有效还原氧化石墨烯, 随着其用量的增加, 氧化石墨烯还原程度增加, 碳/氧摩尔比升高, 片层间距减小, 热稳定性增强, 导电率增大(可达3.6×102 S/m). 还原后部分氧化石墨烯片层发生聚集.

Abstract:

Graphene oxide reduced by n-butylmagnesium chloride(n-BuMgCl) has been characterized systematically by elemental analysis, Fourier transform infrared spectroscopy(FTIR), X-ray photoelectron spectroscopy(XPS), Raman spectroscopy, X-ray diffraction(XRD), solid-state13C nuclear magnetic resonance(13C NMR), thermal gravimetric analysis(TGA), electrical conductivity measurement and atomic force microscopy(AFM). The results indicate that n-BuMgCl has a good efficiency in the reduction of graphene oxide. With the increase of n-BuMgCl concentration, the C/O molar ratio of the reduced graphene oxide(rGO) increased, and the interlayer distance of the rGO sheets decreased. The thermal stability of rGO has been improved significantly and the electrical conductivity of rGO increased to 3.6×102 S/m. AFM images show that the thickness of rGO sheets is larger than that of GO due to aggregation.

Key words: n-Butylmagnesium chloride, Graphene oxide, Reduction
