▎ 摘　　要

NOVELTY - A copper oxide-based cellulose modified chitosan bionanocomposite film comprises copper oxide nanoparticles, reduced graphene oxide, cellulose nanocrystals (CNC), and chitosan-based polymer matrix. The film comprises 0.01-0.03 M copper nanoparticles incorporated in polymer matrix, and 1 wt.% cellulose nanocrystals and 0.5 wt.% reduced graphene oxide based on weight of chitosan and having film thickness of 80-100 mu m. USE - Copper oxide-based cellulose modified chitosan bionanocomposite film used in antibacterial and soft tissue engineering and packaging applications. ADVANTAGE - The copper oxide-based cellulose modified chitosan bionanocomposite film has excellent biocompatibility and mechanical strength. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating the preparation of copper oxide-based cellulose modified chitosan bionanocomposite film.
