▎ 摘　　要

NOVELTY - Method for preparing graphene oxide fibers by wet spinning, comprises (a) preparing graphene oxide mixtures in solvent chosen from water, N-methyl-2-pyrrolidone, and/or N,N-dimethyl formamide, which the concentration of graphene oxide of 5-30 mg/ml, and (b) injecting the graphene oxide mixtures obtained from step (a) through a nozzle with a diameter of 0.5-1.5 mm at a speed of 0.1-0.5 ml/minute into a coagulation bath rotated at 5-30 rpm to obtain graphene oxide fibers, where the coagulation bath comprises a coagulant of a silver nitrate in a solvent mixture of ethanol and water with a volumetric ratio of ethanol to water of 1:1-1:5, and the concentrations of silver nitrate solution is 0.1-0.5 Molar. USE - The method is used for preparing graphene oxide fibers by wet spinning. ADVANTAGE - The method prepares graphene oxide fibers by wet spinning technique using a coagulant to fabricate graphene oxide fibers with consistent length that can maintain their shape continuously without the use of additives while sustaining good electrical conductivity.
