Micro-structures of the CuCl_2-GICs on TEM

CHUAN Xiu-Yun(Department of Geology , Division of Mineral Materials, Peking University, Beijing 100871, China)  
The layer and in-plane structure of CuCl2-GICs, synthesized with expanded graphite,was detected by TEM. The I_c values of the 2-,3-,4-stage CuCl2-GICs calculated on the X-raydiffraction patterns was similar to the theoretical values. The parameter of the in-plane structurewas calculated on the selected area electron diffraction pattern. The diffraction spots of the GICsconsist of single spots of carbon atom plane of graphite and triple spots of chloride. The singlespots imply that carbon atom of the in-plane of GICs is put in the order of the hexagonal net ofgraphite. Compared with the size of carbon atom, the triple spots of chloride signify that thereare three sizes of the molecule of cupric chloride. According to the lattice of CuCl2-GICs, thereare three kinds of super-structure:(2x2)R(30°), (7 x7)R(0°), (3 x 3)R(0°). The angles ofthe lattice of cupric chloride and carbon atom are 30° in the 2-stage and 3-stage CuCl2-GICs, 0°in. 1-stage CuCl2-GICs. According to electron diffraction pattern, high resolution image, chemicalcompounds analyses, XPS-ESCA and XAES, the frame of micro-structure of the CuCl2-GICs wasmade.
