▎ 摘　　要

NOVELTY - Preparation of graphene oxide surface graft-modified aramid fiber involves providing tris hydrochloride solution having pH of 8.5, adding aminated graphene oxide, dipping dopamine modified aramid fiber in the obtained solution, and reacting at 15-50 degrees C for 10-24 hours. The aminated graphene oxide is obtained by adding graphene oxide in aqueous solution, obtaining graphene oxide suspension, ultrasonic processing for 30-60 minutes, adding amine reducing agent at 3-100 degrees C, mechanically stirring for 6-24 hours, cleaning, and drying. USE - Preparation of graphene oxide surface graft-modified aramid fiber (claimed). ADVANTAGE - The graphene oxide surface graft-modified aramid fiber having excellent adhesiveness and uniform surface is prepared by simple method.
