Intercalation and Electrical Properties of Highly Ordered Graphite Fibers

摘要

Vapor-grown carbon fibers have been obtained by pyrolysis of hydrocarbon such as benzene and methane with catalytic effect of ultra-fine metal particles. Two different methods have been established for successful formation of the fibers. By the substrate method, thick fibers and long fibers can be grown. By aerosol system, where the catalytic particles are floating in the reaction chamber, very thin in diameter and less than several mm in length have been effectively produced. These carbon fibers from gas phase have a high degree of preferred orientation and exhibit a high graphitizability enough for intercalation. These intercalated vapor-grown carbon fibers show high electrical conductivity and mechanical performances.
