NOVELTY - Preparing composite modified fiber containing graphene oxide-metal organic framework, comprises (i) subjecting fiber for ammonia plasma treatment, (ii) preparing graphene oxide and metal organic frame (MOFs), 2-methylimidazolium zinc salt (zeolitic imidazole framework-8 (ZIF-8)) mixed suspension, and spraying the suspension on the treated fiber and drying, (iii) immersing obtained product in an amine salt-containing N,N-dimethylformamide solution for catalytic reaction, and (iv) taking out after catalytic reaction, washing by N,N-dimethylformamide solvent, and drying to obtain composite modified fiber containing graphene oxide-metal organic framework. USE - The composite modified fiber is useful for preparing the surface covering layer of the dressing or medical clothing (claimed), preferably preparation of antibacterial material. ADVANTAGE - The composite modified fiber has excellent antibacterial properties, has zeolitic imidazole framework material providing permanent porosity, high surface area, hydrophobicity, open metal sites and water stability, and has long antibacterial time.
