▎ 摘　　要

NOVELTY - Preparation of graphene-polyacrylonitrile-based composite carbon fiber comprises preparing surface-modified graphene, reacting with acrylonitrile monomer in first organic solvent, spinning obtained composite into fiber, and subjecting to pre-oxidation and carbonization. USE - Method for preparing graphene-polyacrylonitrile-based composite carbon fiber (claimed). ADVANTAGE - The fiber has higher mechanical property in comparison to prior art, and increase in monofilament strength of 8% and modulus of 10%.
