以氧化石墨烯为前躯体,利用热膨胀法制备出热膨胀石墨烯(RGO),并通过红外光谱、X射线光电子能谱技术、X射线衍射、拉曼光谱、扫描电镜、透射电镜和比表面积(BET)对其进行表征。结果表明:所制备的热膨胀石墨烯为无定型碳结构,存在少量含氧官能团,缺陷较多,表面形貌类薄纱状,并伴随着褶皱和层叠,为多层结构,层数大约为10层,层间距约为0.4nm,比表面积为223cm2/g,孔径分布以介孔为主。
The thermal expansion graphene (rGO)was prepared by thermal expansion which graphene oxide used as precursor,and characterized by FT-IR,XPS,XRD,Raman,SEM,TEM and BET.The results shown that the rGO was an amorphous structure with a small number of oxygen-containing functional groups and a certain amount of defects.The morphology of the rGO was transparent tulle,and there were also wrinkles and overlaps on its surface.The number of the rGO layers was about 10 and the interlay spacing was around 0.4nm.The specific surface area of the rGO was 223 cm2/g,and the pore size distribution was mainly mesoporous.
