Antibacterial performance of silver incorporated and poly(vinylidene fluoride-co-hexafluoropropylene) films

The application of silver nanoparticles in food packaging has emerged as a viable strategy for improving public health safety, notably in combating modern antimicrobial resistance activities of Escherichia coli and Staphylococcus aureus infection. The development of silver nanoparticle-embedded and poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) films represents a promising advancement in food packaging, aimed at addressing the critical challenge of antimicrobial resistance, particularly against Staphylococcus aureus infections. This study focuses on creating a novel composite polymer material with strong antibacterial properties by incorporating silver nanoparticles into PVDF-HFP films. Inspired by nature’s antibacterial mechanisms, such as the nanoscale topographies of dragonflies and cicada wings that mechanically disrupt bacterial membranes, this research integrates microstructure polymer surfaces to enhance the antibacterial efficacy of silver nanoparticles. Through controlled experiments, the bactericidal performance of the developed material was evaluated, demonstrating significant reductions in S. aureus populations without adverse effects on human health. The results confirm the potential of silver nanoparticle-based films as an effective and environmentally friendly alternative to traditional chemical disinfectants. This innovative material offers a sustainable solution to enhance food safety and mitigate the risks associated with antimicrobial-resistant pathogens, positioning silver nanoparticles as a vital tool in advancing public health and food security
