NOVELTY - Graphene-nano silver modified chitosan-cellulose antibacterial film comprises 0.5-3 pts. wt. nano-silver loaded modified graphene, 22-30 pts. wt. chitosan, 7.5-15 pts. wt. glutaraldehyde, and 52-70 pts. wt. carboxymethyl cellulose. USE - Used as graphene-nano silver modified chitosan-cellulose antibacterial film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene-nano silver modified chitosan-cellulose antibacterial film comprising (i) adding 0.5-3 pts. wt. nano-silver-loaded modified graphene to distilled water solvent, after ultrasonic dispersion is uniform, adding 22-30 pts. wt. chitosan, adding acetic acid until chitosan is dissolving, adding 7.5-15 pts. wt. glutaraldehyde is using as a crosslinking agent, heating to 50-90 degrees C, reacting for 8-15 hours, removing solvent, washing and drying to prepare nano-silver loaded modified graphene cross-linked chitosan, and (ii) adding nano-silver loaded modified graphene cross-linked chitosan and 52-70 pts. wt. carboxymethyl cellulose to distilled water solvent, stirring at 30-50 degrees C for 15-25 hours, and pouring solution into polytetrafluoroethylene, in the film mold, drying and curing to form a film to prepare a graphene-nano silver modified chitosan-cellulose antibacterial film.
