Preparation of Cellulose Acetate Nanocomposite Films Based on TiO2-ZnO Nanoparticles Modification as Food Packaging Applications

To develop bio-packaging materials, nanocomposite films of cellulose acetate reinforced with titanium dioxide and zinc oxide nanoparticles were prepared, by the casting method at different weight ratios ZnO (1.5, 2, 2.5) wt% a constant ratio 2 TiO2. TiO2 tested using scanning electron microscopy (SEM). The mechanical properties (tensile strength elongation) improved fixed level Cellulose Acetate+ 2% TiO2+1.5wt% loading. Beyond that loading, they decreased. tensile was decreased due to some degrees agglomeration filler particles above critical content. Fourier-Transform Infrared Spectroscopy (FTIR) conducted reveal microstructures chemical composition as-prepared composite films. wettability also determined sessile drop method. An increase in contact angle observed addition content from 70.6° 77.1° compared pure Acetate, which indicated value 61.3°. Antibacterial activity against Escherichia coli Staphylococcus aureus enhanced after incorporation ZnO-TiO2 CA. antibacterial prepared suggest could be used for packaging applications.
