摘要
采用定量混合法,以微粉石墨为主体材料合成出2、3阶CuCl2 NiCl2 GIC,应用XRD技术对其层间结构进行表征,结果证实所得产物以混阶形式存在,其中2、3阶CuCl2 NiCl2 GIC的特征层间距为1.474nm和1.753nm。用扫描电镜观测样品的表观形貌,并进行选区成份分析。通过考核CuCl2 NiCl2 GIC的粒度分布、沉降速度及质量消光系数,证实该物质对工作在红外波段的军用电子器材具有良好的干扰功效。
The super-fine graphite is used as main body to synthesize the acceptor GIC of CuCl_2-NiCl_2 by means of ration-blend method. The layer structures of samples are investigated by Xray diffraction (XRD). The results show that their stage structures are 2, 3 stage co-existentones,and the characteristic layer distance of 2,3 stage CuCl_2-NiCl_2-GIC is 1.474nm and 1.753nm. With scanning electronic microscopy (SEM), the surface figures of GIC are observed. Moreover, the relative content of elements is measured. It has been proved that CuCl_2-NiCl_2-GIC can effectively interfere the military electronic equipments in the IR range through examining the material's granularity, fall rate and mass extinction.
