Influence of BSA coated ZrO2 on structure mechanical wettability and thermal properties of PVC and PVA nanocomposites Zahra Hajjari zahra hajjari1992@gmail com Department of Chemistry Isfahan University of Technology Isfahan 84156 83111 I R IranDegree M Sc Language FarsiSupervisor Prof Shadpour Mallakpour E mail mallak@cc iut ac ir mallak777@yahoo com mallakpour84@alumni ufl eduAbstract This present thesis describes the fabrication of novel nanocomposites NCs based on poly vinyl chloride PVC and poly vinyl alcohol PVA as a polymer matrix and variety percentages 3 6 and 9 wt of ZrO2nanoparticles NPs modified with bovine serum albumin BSA ZrO2 BSA NPs as a beneficial filler usingsonication method The products were characterized by several analyses Thermogravimetric analysis of theobtained PVC ZrO2 BSA and PVA ZrO2 BSA NCs showed the higher thermal stability of them comparedto the neat PVC and PVA Transmission electron microscopy displayed a decrease in the particle size ofZrO2 BSA NPs after incorporating inside the polymers Increase in The optical and mechanical propertieswere indicated by UV Visible spectroscopy and tension test Contact angle test was showed that thehydrophilicity of obtained NCs was increased by adding the ZrO2 BSA NPs In addition the Fouriertransform infrared field emission scanning electron microscopy X ray diffraction and energy dispersive X ray spectroscopy analyses were studied to investigate the morphology and structure properties of samples These changes in the PVC and PVA properties are related to the homogeneous dispersion of ZrO 2 BSA NPsinto the matrix under ultrasonication with the power of 50 W Keyword zirconia bovine serum albumin PVC PVA nanocomposite Ultrasonic irradiation greenchemistry thermal stability
