Integration of ZnO‐Ag Nanocomposites into PMMA Thin Film for Enhanced Antibacterial Applications

Abstract The exploration of advanced materials has become imperative for addressing challenges in diverse fields, including healthcare and infection prevention. This research contributes to this domain by focusing on the synthesis, characterization, and evaluation of ZnO‐Ag nanocomposites and embedding them in PMMA matrix to obtain free‐standing flexible membrane with enhanced antibacterial potential and reusability of material. The study employs a solvothermal method for the decoration of silver nanoparticles onto zinc oxide nanorods, with the objective of harnessing the synergistic antibacterial properties of both materials. The study evaluates the antibacterial potential of the nanocomposites through well diffusion and growth kinetic assays, revealing their enhanced efficacy with a zone of inhibition (ZOI) of 21 ± 1.05 mm against Escherichia coli (E. coli) . The implications of this research extend to the realm of biomedical applications, positioning the nanocomposite‐polymer membrane as promising candidates for infection prevention in healthcare premises.
