Nanocomposite of PVA/PVP blend incorporated by copper oxide nanoparticles via nanosecond laser ablation for antibacterial activity enhancement

This work makes an investigation of Polyvinyl Alcohol (PVA)/Polyvinyl Pyrrolidone (PVP) composite scattered by copper oxide nanoparticles. Spectroscopic techniques have been utilized for studying the mechanism reaction between PVA/PVP and CuO NPs. Cell viability antibacterial assessment are used investigating activity nanocomposite systems. XRD FTIR-ATR approved complexation miscibility PVA, PVP, NPs UV–Vis spectra embedding into appearance additional peak at 336 nm. Optical parameters bandgap calculation indicate that decrease crystallinity system. DSC measurements were also studied to reveal thermal stability prepared sample. The inhibition zone values E. coli S. aureus microorganisms increased increasing ratio in 18.5 ± 0.5 20.4 6.0. responses fibroblast cell line synthesized nanocomposites showed capacity PVA/PVP/CuO be recommended biomedical applications.
