NOVELTY - Preparing graphene modified fiber/fabric involves placing fiber/fabric in a dye with reactive groups for dip dyeing. The impregnated fiber/fabric is immersed in a functionalized graphene solution for reaction, the reacted product is subjected to color fixation treatment, and product after the fixation treatment is subjected to reduction treatment to obtain the graphene modified fiber/fabric. USE - Method for preparing graphene modified fiber/fabric. ADVANTAGE - The method enables to prepare graphene modified fiber/fabric, which improves adhesion of the functionalized graphene on the fiber/fabric surface, has good washing resistance and improves the service life of the material, has simple process, low cost, easy large-scale production, low energy consumption, easy waste water treatment, and has good application prospects.
