NOVELTY - Method of preparing graphene-modified cellulose fiber involves: (a) performing acid pre-treatment of fiber, and washing with water until the pH value is 6.5-7.5 to obtain pre-treated fiber; (b) adding sodium hydroxide, hydrogen peroxide solution, hydrogen peroxide solution stabilizer, magnesium sulfate heptahydrate, and graphene solution, and mixing; (c) performing microwave radiation to the mixed solution, where the concentration of alkali-oxygen first-bath solution is 5-8 g/L, and the bath ratio of alkali-oxygen first-bath solution to the pre-treated fiber is 18-25:1; and (d) beating mixed solution, water washing, acid washing, and drying. USE - Method of preparing graphene-modified cellulose fiber.
