ABSTRACT:
Low cost, high break elongation graphitized carbon fibers having low degree of graphitization are inert to bromine at room or higher temperatures, but are brominated at -7.degree. to 20.degree. C., and then debrominated at ambient. Repetition of this bromination-debromination process can bring the bromine content to 18%. Electrical conductivity of the brominated fibers is three times of the before-bromination value.
