Abstract
The present study aims to investigate the influence of Zinc Oxide nanoparticles (ZnO NPs) on the physicochemical properties of poly(vinyl alcohol)/Spathodea campanulata bud fluid (PSC) matrix. The FITR study assured the physical interaction between ZnO NPs and the PSC matrix. Tensile strength was enhanced by 18% with the incorporation of ZnO NPs into the PSC matrix. The DSC measurements depicted an increased glass transition temperature than PSC matrix at lower content of ZnO NPs. The thermal stability of nanocomposite films was remarkably improved (about 50 °C). The XRD results depicted the homogeneous distribution of ZnO NPs in the PSC matrix. The morphology studies revealed the homogeneity due to good dispersion of ZnO NPs. The water contact angle findings shown the nanocomposite films were hydrophilic. The nanocomposites have shown only 2.8% solubility in water. The WVTR of nanocomposite films was improved by 56%. The bionanocomposite films exhibited good antibacterial activity and excellent preservation capacity and could be a potent alternative to the nonbiodegradable packaging material.
