Electrical Properties and Structure of Intercalated Pitch-Based Carbon Fiber

The intercalated pitch-based carbon fiber(CF)of high conductivity was prepared by the molten salt method with CuCl₂-KCl system. In the X-ray diffraction pattern of this intercalated pitch-based CF, the width of (002) and (10) diffraction lines decreased by comparing with the pristine state. The mechanism of decrease of the widths of these diffraction lines was that the cause of high conductivity of pitch-based CF is the formation of the graphite intercalated compounds (GIC).
