利用氧化石墨的层离特性,采用化学还原法制备了石墨薄片材料,并采用红外光谱、X射线衍射、元素分析、透射电镜、原子力显微镜和扫描电镜对产品进行了表征和分析.结果表明,制备出的石墨薄片直径为1～3μm,厚度为2～4nm,为层状结构的非晶体,具有褶皱的固有属性,且极易发生团聚现象.
Graphite nanosheets are synthesized by chemical reduction method using the layer-separation characteristics of graphite oxide. The products are characterized by FT-IR, XRD, elementary analysis, TEM, AFM and SEM. The results show that the graphite nanosheets with a diameter of 1～3μm and the thickness of 2～4nm, are amorphous body with layered structure and corrugation morphology and easily aggregated together.
