摘要：

In this study, antimicrobial hybrid nano-materials were prepared by one-pot syntheses of silver (Ag), copper oxide (CuO), or zinc oxide (ZnO) nanoparticles (NPs) during regeneration of cellulose from cotton linter (CL) and microcrystalline cellulose (MCC). SEM micrographs indicated that the metallic nanoparticles were attached to the surface of the regenerated cellulose. EDX and ICP results showed that more AgNPs were adsorbed on the cellulose than CuONPs or ZnONPs. FTIR results revealed that the metallic nanoparticles were attached to the cellulose through the interaction with the hydroxyl group of cellulose. XRD results showed the characteristic diffraction peaks of individual metallic nanoparticles. The thermal stability of the R-CL and R-MCC increased in the hybrids with AgNPs and ZnONPs. The R-cellulose/metallic NPs hybrids showed strong antibacterial activity against E. coli and I. monocytogenes. Thus, the hybrid nano-materials can be used as nanofillers for the preparation of antibacterial packaging films. (C) 2017 Elsevier B.V. All rights reserved.
