摘要: 采用熔鹽法,在CuCl2-KCl系中得得較高電導率的插層瀝青基碳纖維.與原始狀態相比,插層后的瀝青碳纖維x射線衍射圖譜上的(002)及(10)衍射線的寬度變小,衍射寬度變小的機制是由于石墨層間化合物的形成,使瀝青基碳纖維電導率增加。

Abstract: 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). -
