摘要: 采用Hummers修正法制备氧化石墨烯(GO),用壳聚糖(CS)作为“绿色”无毒还原剂,以反应温度和反应时间来控制氧化石墨烯的还原程度。用红外光谱、紫外可见吸收光谱、拉曼光谱和X射线衍射等多种表征手段研究不同还原程度的还原氧化石墨烯的结构与性能。结果表明,改变温度不能有效地控制氧化石墨烯的还原程度;在50℃低温环境下,控制反应时间可以得到不同还原程度的还原氧化石墨烯,为进一步研究不同还原程度还原氧化石墨烯的非线性光学性质奠定了基础。

Abstract: Graphene oxide (GO) was prepared by modified Hummers,the reduction of GO was developed by using chitosan (CS),which is nontoxic and environment-friendly as a “green” reducing agent. And the reduction degree of GO was controlled by the temperature and time of reaction. The RGO was characterized with Fourier transform infrared spectroscopy,X-ray diffraction spectroscopy,UV visible absorption spectroscopy,and Raman spectroscopy. Analysis shows that the change of temperature could not effectively control the reduction degree of GO. In 50℃ low temperature environment,the different reduction degrees of reduction graphene oxide could be obtained by controlling the reaction time,this result lay the foundation for the study of nonlinear optical properties of different reduction degree RGO.

Key words: graphene oxide, graphene, controllable reduction
