The present invention discloses high-strength graphene oxide composite fibers, their preparation methods, and applications, belonging to the technical field of graphene composite fibers. Mix 90-100 parts of polyethylene terephthalate slices, 3-8 parts of additives, and 0.02-0.08 parts of catalyst, and inject them into a twin-screw extruder for extrusion and melt spinning to obtain composite fibers. The synergistic effect of graphene oxide and flame retardant elements such as P and Si enhances the flame retardancy of composite fibers; Graphene oxide and quaternary ammonium salts with long alkyl chains work together to enhance the antibacterial properties of composite fibers; Long carbon chains increase the toughness, flexibility, and resilience of composite fibers; Additives can be highly dispersed in the matrix resin and firmly bonded with the matrix resin, thereby fully, stably, and long-term exerting corresponding effects, such as improving the strength and mechanical properties of composite fibers, increasing the toughness, softness, and rebound rate of composite fibers, enhancing the wear resistance, antibacterial properties, flame retardancy, and stability of composite fibers, and so on.
