摘要

采用高温炭化和Hummers氧化还原法制备玉米粉石墨烯(CG)。通过有机元素分析、X射线光电子能谱(XPS)、X射线衍射(XRD)、拉曼光谱、原子力显微(AFM)和透射电镜(TEM)对所制备的玉米石墨烯进行组成元素、结构和形貌进行分析。结果表明:CG碳含量由原来的57.6%(玉米粉)到95.1%,增加了37.5%;CG在23.08°的(002)晶面具有石墨烯的衍射峰,且拉曼测试具有D峰和G峰,D峰与G峰的强度比ID/IG为1.19,CG试样晶格间距大于商品石墨烯的晶格间距,CG约3层,层间距在1.21nm左右,证明所制备的CG为石墨烯,且玉米粉石墨烯要比商品石墨烯薄,可应用于医用和耐高温的航空航天领域。

Abstract

The corn flour graphene (CG) was prepared by high temperature carbonization and Hummers redox method.The elements,structure and morphology were studied by the organic elements analysis,X-ray photoelectron spectroscopy (XPS),X-ray diffraction (XRD),Raman spectroscopy,atomic force microscopy (AFM) and transmission electron microscopy (TEM).It was found that the carbon content of CG increased from 57.6% (corn flour) to 95.1%,as increase of 37.5%.There was a diffraction peak of graphene on the (002) crystal surface at 23.08°.The D and G peaks of Raman test existed,and the ID/IG of the peak intensity ratio was 1.19.The lattice distance of the CG sample was larger than that of commercial graphene (GE),the CG was about three layers with the layer spacing of 1.21nm.It proved that the obtained CG was the graphene.And the CG was thinner than GE.It can be used in the medical and high temperature resistant aerospace fields.
