摘要
采用熔盐法,在CuCl2─KCl系中得得较高电导率的插层沥青基碳纤维.与原始状态相比,插层后的沥青碳纤维x射线衍射图谱上的(002)及(10)衍射线的宽度变小,衍射宽度变小的机制是由于石墨层间化合物的形成,使沥青基碳纤维电导率增加。
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).
