    • In accordance with the present invention, there are provided activated carbon fibers consisting of optically anisotropic components and optically isotropic components by spinning a spinning pitch into pitch fibers, and infusibilizing the resulting fibers, followed by activation treatment. The spinning pitch is prepared by melt mixing together (A) 100 parts by weight of an optically isotropic pitch having a softening point of 230-300°C obtained by heat treatment of a pitch while blowing an oxygen containing gas into the pitch and (B) 10-50 parts by weight of an optically isotropic pitch having a softening point of 200-270°C and preferably obtained by polymerization of naphthalene in the presence of a Lewis acid catalyst. Also according to the invention, carbon fibers consisting of optically anisotropic components and optically isotropic components are prepared by spinning the above-mentioned spinning pitch into fibers, and infusibilizing the resulting pitch fibers, followed by carbonization and/or graphitization.
    • 在本发明雅舞蹈,提供活化的碳纤维通过纺丝的纺丝沥青成沥青纤维,和难熔化所得到的纤维,随后活化处理由...组成的光学各向异性元件和光学各向同性分量。 纺丝沥青通过熔融重量份(A)100份混合的光学各向同性沥青一起具有同时吹入含氧气体进入音调,并通过节距的热处理获得的230的软化点为300℃,制备(B )10-50重量份的具有200的软化点为270℃,且优选通过萘的聚合在路易斯酸催化剂的存在下获得的光学各向同性沥青中。 所以gemäß发明,其由光学各向异性元件和光学各向同性分量的碳纤维是通过上述的纺丝沥青纺成纤维,和难熔化所得沥青纤维制备,然后通过碳化和/或石墨化。
