Synthesis of Antimicrobial and Biodegradable Polyhydroxybutyrate Films Embedded with Zinc Oxide NPs by Casting Method

This study explores the development of novel biodegradable and antimicrobial materials for personal protective equipment (PPE), focusing on environmental sustainability and biological resistance. The research introduces an innovative approach using biodegradable polyhydroxybutyrate (PHB) polymer, combined with Zinc Oxide (ZnO) NPs to enhance antibacterial properties. The report categorizes various antibacterial materials, emphasizing the unique qualities of PHB as a biodegradable alternative to petrochemical-sourced plastics. Additionally, it delves into the mechanisms of antibacterial action of ZnO NPs, highlighting their effectiveness in generating reactive oxygen species (ROS) and Zn2+ ions to combat bacterial threats. The study concludes with the successful synthesis of PHB films embedded with ZnO NPs, demonstrating their potential as a sustainable and effective solution for PPE in response to the increasing demand for environmentally friendly and biologically resistant materials.
