▎ 摘  要

NOVELTY - Preparing graphene composite acetate ultrafiltration adsorption fiber comprises (i) selecting each raw material comprising cellulose acetate, graphene, dichloromethane, acetone, calcium carbonate, and N-N-dimethylformamide, (ii) adding dichloromethane to acetone, and stirring uniformly to obtain a dichloromethane acetone solution, (iii) adding cellulose acetate, calcium carbonate, and graphene powder to the dichloromethane acetone solution, and fully stirring, (iv) adding N-N-dimethylformamide to the solution obtained in Step (iii), and continuously stirring to obtain a cellulose acetate spinning solution, and (v) using cellulose acetate spinning solution obtained in step (iv) for spinning, and then dissolving the calcium carbonate to obtain finished product. USE - The method is useful for preparing graphene composite acetate ultrafiltration adsorption fiber. ADVANTAGE - The method: improves the adsorption performance of the acetate fiber, and filtering and absorbing efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene composite acetate ultrafiltration adsorption fiber prepared by the above mentioned method.
