FUSION OF ZNO NANO/MINT EXTRACT LOADED PVP/PVA COMPOSITE BLEND: CHARACTERIZATION AND ANTIMICROBIAL ACTIVITYAbstract
ZnO is used as a nanofiller in various concentrations to create flexible self-standing films of PVP-PVA mix composites. This work presents the results of structural, compositional, morphological, and optical analyses carried out using X-ray diffraction (XRD), Fourier Transform Infra-Red spectroscopy (FTIR), scanning electron microscopy (SEM), Thermo gravimetric analysis (TGA), and ultraviolet-visible spectroscopy (UV-vis). The XRD data show that ZnO nanoparticles are produced in the polymeric matrix with hexagonal phase. ZnO nanofiller is dispersed throughout the polymer matrix, as seen in SEM pictures. UV-vis spectra show that the nanocomposite films’ wavelength absorption peak is between 235 and 370 nm. The blue shift may be seen with a drop in the nano filler’s concentration.
