The present invention aims to provide a method for preparing a bio-based material which includes the steps of extracting celluloses from lignocellulosic biomass and regenerating a cellulose film. After that, preparing a metal-graphene oxide nano-composite and subsequently mixing the metal-graphene oxide nano-composite into the cellulose film solution to form an interaction mixture. Subsequently, the interaction mixture is coagulated in a non-solvent coagulant, and a highly porous structure of a cellulose membrane is regenerated. Particularly, the regenerated cellulose membrane has anti-bacterial properties and is tested against Gram-positive and Gram-negative bacteria. |
