▎ 摘　　要

NOVELTY - A graphene oxide modified polyacrylonitrite (PAN) carbon fiber precursor is prepared by dispersing graphene oxide in solvent, uniformly performing ultrasonic dispersing, and preparing graphene oxide PAN spinning original solution; and spinning original liquid by denitriding and defoaming by wet spinning process, washing by water, and drying to obtain desired precursor. USE - Method for preparation of graphene oxide modified polyacrylonitrite (PAN) carbon fiber precursor (claimed). ADVANTAGE - The method has simple technique and low cost, and is suitable for industrial production. The prepared precursor has high orientation degree. Intensity is high and heat stabilization process is not easy to deoriented.
