Characterization and evaluation of electric-arc-produced graphene material

摘要: 针对一种电弧法制备的石墨烯材料, 通过X射线光电子能谱、 拉曼光谱、 红外光谱和扫描电镜分析等方法进行了表征与评价.结果表明: 石墨烯中C元素含量为 89.77%, O元素和N元素含量分别为3.03%和7.21%; 通过拉曼光谱中G峰和2D峰的位置确定石墨烯样品以多层石墨烯为主; 红外光谱显示石墨烯样品吸附了水分子; 显微结构观察确定了石墨烯片层结构的层数及尺寸.根据实验方法总结了一套石墨烯的测试表征方案, 为石墨烯在复合材料中的推广应用提供了评价依据.Abstract: The electric-arc-produced graphene materials were characterized and evaluated by a series of methods such as X-ray photoelectron spectroscopy, Raman spectra, infrared spectroscopy and scanning electron microscope analysis. Results show that the content of C element in graphene is 89.77%, and those of O and N elements are 3.03% and 7.21%. The sample has been identified as multilayer graphene-based Raman spectra G peak and 2D peak position. Adsorption of water in graphene sample is also detected by infrared spectroscopy. The layer number and size of graphene layer structure are observed through microscopic observation. This paper summarized a series of test schemes to characterize graphene,which provides a basis of evaluation for the dissemination and application of graphene in composites.
