Abstract

The development of biodegradable packaging materials is important to mitigate the negative environmental impact of plastic waste. This study focuses on enhancing antimicrobial and physical properties of poly(butylene adipate-co-terephthalate) biodegradable film by incorporated with zinc oxide (ZnO)/reduced graphene oxide (rGO). The resulting nanocomposite films were characterized to evaluate its functional properties and antibacterial activity. The ZnO/rGO nanocomposite can improved the mechanical and thermal properties of the PBAT nanocomposite films. In addition, the migration of Zn ions from the PBAT/ZnO/rGO nanocomposite films were considered safe under the criteria established by European plastic regulation (EU) standards. The PBAT/ZnO/rGO nanocomposite films also showed excellent antibacterial activity against Escherichia coli (81.32%) and Staphylococcus aureus (82.44%). The results of this study suggest that PBAT/ZnO/rGO nanocomposite films is effective as a biodegradable active material for food packaging applications.
