Distribution of intercalant in copper chloride and iron chloride graphite intercalation compounds

CuCl2 and FeCl3 graphite intercalation compounds were prepared by a gas pha se reaction method using different carbon host materials. The effect of the microstructure of carbon host materials on the amount of intercalation and the distribution of intercalant was investigated using x-ray diffraction a nd electron microprobe analysis. For a fiber sample with a core region of o nion skin structure in the cross section, a lower concentration of intercal ant was measured in the core region. For fiber samples with an oriented-cor e transverse microtexture. different intercalant distributions along the lo ng axis (oriented-core direction) and the short axis of the elliptical cros s section were found.
