▎ 摘　　要

NOVELTY - Preparation of graphene oxide-chemically-modified polyimide fibers involves modifying surface of polyimide fibers with graphene oxide by chemical grafting, such that surface roughness of the polyimide fibers is enhanced, surface energy is reduced, and hydrophilicity and specific surface area are improved. USE - Preparation of graphene oxide-chemically-modified polyimide fibers used for reinforcing thermoplastic material.
