摘要
用化学氧化法制备氧化石墨烯,并用一种新型的低温化学还原方法将其还原。用红外光谱、拉曼光谱、X射线衍射、X射线光电子能谱、扫描电镜、原子力显微镜等多种手段表征氧化石墨烯和还原氧化石墨烯的结构与形貌。结果表明,即使在低温条件下,壳聚糖依然可以还原氧化石墨烯,从而预示,在低温条件下,能够在同一环境下实现氧化石墨烯的还原和石墨烯的应用。
Graphene oxide（ GO） is prepared by the modied Hummers method and reduced by a new lowtemperature chemical reduction. The structure and morphology of GO and reduced graphene oxide（ r GO） was characterized by FT IR,XRD,Raman,XPS,SEM and AFM. Results showed GO can be reduced by using chitosan as the reductant even at low temperature environment. This means the reduction of GO and application of graphene can be realized concurrently at same one low temperature environment.
