▎ 摘　　要

NOVELTY - Preparation of cellulose-based material involves extracting celluloses from a lignocellulosic biomass to remove lignin from the biomass, treating the extracted celluloses in an alkali solution to form a liquid solution, drying the liquid solution to form a powder material, pre-cooling one or more aqueous solvents comprising a mixed aqueous sodium hydroxide solution and urea solution and/or a mixed aqueous lithium hydroxide solution and urea solution, dissolving the powder material in the pre-cooled aqueous solvent to form a solution (s1), pre-cooling the solution (s1) to form a solid form, thawing the solid form at room temperature to obtain a transparent cellulose solution, mixing a metal-graphene oxide nanocomposite, preferably silver-graphene oxide nanocomposite with the cellulose solution to form an interaction mixture, and coagulating the interaction mixture in a non-solvent coagulant comprising an acidic solution to form a regenerated cellulose based material. USE - Preparation of cellulose-based material used as functional additive and ingredient. Uses include but are not limited to pharmaceutical preparation, cosmetic preparation, food preparation, building material, varnish, paint, coating compound and polymer. ADVANTAGE - The method enables simple and economical preparation of cellulose-based material having excellent antibacterial property against Gram-positive bacteria and Gram-negative bacteria, and improved transparency and tensile strength.
