NOVELTY - Antibacterial graphene oxide nanocomposite fabric comprises composite fabric which improves the dispersibility of graphene oxide by solution ultrasonic blending method, prepare silver nanoparticles by microwave heating synthesis method. The graphene oxide-polyethyleneimine -silver based nanocomposite (GO-PEI-Ag) are prepared by freeze-drying. The GO-PEI-Ag nanocomposite material is dissolved in ultrapure water, sprayed on cotton and bundled into antibacterial cotton yarn, and weaved antibacterial cotton yarn into antibacterial graphene oxide nanocomposite fabric by woven method. USE - Antibacterial graphene oxide nanocomposite fabric. ADVANTAGE - The antibacterial graphene oxide nanocomposite fabric has efficient antibacterial and deodorizing effect, and the green synthetic process protects the ecological environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the antibacterial graphene oxide nanocomposite fabric, which involves: (A) dissolving GO in ultrapure water, and forming GO dispersion under ultrasonic conditions, and adding PEI solution for blending, adjusting pH to 6-10, and the interval is 20 minutes, stirring at room temperature for 20-30 hours to obtain GO-PEI dispersion liquid, and freeze-drying to obtain GO-PEI powder; (B) dissolving silver nitrate in ultrapure water, dropping ammonia into the silver nitrate solution under shaking conditions, and adding dropwise until the initial precipitation completely disappears as the termination point, forming diammine silver hydroxide ((Ag(NH3)2)OH) solution; (C) dissolving the GO-PEI powder in ultrapure water, sonicating for 30 minutes to form a uniform dispersion of GO-PEI, then adding 1mL of the (Ag(NH3)2)OH solution dropwise After ultrasonic blending, reacting with a microwave synthesizer and naturally cool to room temperature to obtain the original reaction solution of GO-PEI-Ag, and obtaining GO-PEI-Ag nanocomposite; (D) dissolving GO-PEI-Ag nanocomposite in ultrapure water,where spinning solution is prepared, and the nanofiber yarn is prepared by an electrostatic spinning process; and (E) weaving nanofiber yarn using a woven method to obtain an antibacterial graphene oxide nanocomposite fabric.
