▎ 摘  要

NOVELTY - Graphite fiber comprises carbon fiber which is linear and tightly coated on graphene sheet outside carbon fiber, where carbon fiber and graphene layers form graphite fiber. USE - Graphite fiber. ADVANTAGE - The graphite fiber is cost effective, has excellent mechanical property and high flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing graphite fiber, which involves: (A) dissolving 12-16 wt.% polyacrylonitrile in N,N-dimethylformamide (DMF) and stirring to obtain precursor solution; (B) mixing precursor solution and metal catalyst substrate, and treating by electrospinning to obtain polystyrene nitrile fiber precursor; and (C) adding metal catalyst lining and polystyrene nanofiber precursor on bottom and aging at 900-1200 degrees C in non-oxidizing gas atmosphere for 3-20 minutes to obtain desired product.
