NOVELTY - Preparation of modified synthetic fiber involves selecting graphene oxide with a particle size of 0.1-6.5 μm to prepare a graphene oxide solution, mechanically crushing synthetic fibers, adding to water to form a suspension, ultrasonically dispersing to obtain a synthetic fiber suspension, mixing the graphene oxide solution and the synthetic fiber suspension to obtain mixed solution, and subjecting to surface modification treatment and reduction treatment at 80-110℃. USE - Preparation of modified synthetic fiber used in medical and textile products. ADVANTAGE - The preparation method is simple and economical, and produces modified synthetic fiber with resistance of up to 1.5×105 Ω, and consumes less energy.
