摘要: 采用改良的 Hummers 法制备氧化石墨烯(GO),再用抗坏血酸(LAA)、茶多酚 (TP)和 LAA/TP 双组分还原体系作为还原剂,将氧化石墨烯还原成石墨烯(RGO),分别 进行导电性能测试、拉曼光谱分析、X 射线衍射分析以及 X 射线光电子能谱分析,并利用 扫描电镜、透射电镜以及原子力显微镜对 LAA/TP 双组分还原体系所制备的 RGO 的形貌 进行了表征. 结果表明,LAA/TP 双组分还原体系之间存在协同作用,其对 GO 的还原效果 优于单组分还原剂,所制备的 RGO 呈单层结构. 文中还对 LAA/TP 体系的协同作用机理 进行了阐释.

Abstract: Oxidized graphene oxide (GO) was prepared by means of the modified Hummers method,and it was re- duced to graphene (RGO) respectively by using ascorbic acid (LAA),tea polyphenols (TP) and the LAA/TP two-component reduction system as a reductant.Then,the conductivity,Raman spectroscopy,X-ray diffraction pattern and X-ray photoelectron spectroscopy of the obtained RGO were determined,and the morphology of the RGO prepared by LAA/TP was also characterized by means of the scanning electron microscopy,the transmission electron microscopy and the atomic force microscopy.The results show that there exists a synergistic effect between the two-component reduction system of LAA/TP,and the reduction effect of the system is better than that with only single component,and that the obtained RGO is of a monolayer structure.In addition,the mechanism of the syner- gistic effect between LAA and TP was also explained.

Key words: monolayer graphene, preparation, ascorbic acid, tea polyphenols, synergistic action
