| 中文摘要 | 采用定量混合法,以鳞片石墨为主体材料制备了FeCl3-GIC,应用XRD技术表征其层间结构,结果证实所得产物的阶结构以3阶为主、混阶共存,3阶FeCl3-GIC的特征层间距为0.945nm。应用振动样品磁强计测试产品的磁性能,结合EDS能谱图分析载流子的浓度变化,建立电荷迁移模型,讨论了石墨插层化合物的导电机理,应用红外热成像仪检测了粉末的干扰效果。研究表明超细粉FeCl3-GIC在军用远红外波段具有显著的消光特性。; The natural graphite was use d as main body to prepare super-fine FeCl_3-GIC by means of ration-blended met hod. The layer structure of samples was investigated by X-ray diffraction. The results show that stage structure is 3 and 4 stage co-existed,and primary eleme nt of product is 3 stage. The lattice distance of 3 stage FeCl_3 -GIC is 0.945 nm. The magnetization intensity and magnetic susceptibility of FeCl_3-GIC were measured with vibration magnetometer. With energy dispersion spectrometer, the concentration change of carriers was shown. The charge transfer model wa s set up and GIC′s conductive mechanism was analyzed. Moreover,the property of super-fine FeCl_3-GIC interfering infrared imaging apparatus was tested. The results show that product can shield photoelectricity instrument at the military far infrared frequency.; 中国博士后科学基金资助项目(2004035085) |
