Herein, two nanobiocomposite films were fabricated using the chitosan (CS) and poly(v inyl alcohol) (PVA) blended polymeric films containing ZnO nanoparticles and characterized. The ZnO NPs were synthesized by a green method using glycerine as a fuel. The XRD pattern of the ZnO NPs was provided to investigate its purity and crystalline structure. The SEM micrographs of the films exhibited that in both cases, the CS-PVA-G-ZnO NPs (2 & 4 %) films have becomes slightly rough films and this is due to the presence of ZnO NPs dispersed within the polymeric matrix. Also, the swelling was the highest in acidic medium but it was decreased in the neutral environment and it had the least value within the alkaline medium.
