65 Sorption of Bovine Serum Albumin on the surface of ZnO nanoparticles and their application for the production of poly vinyl chloride and poly vinyl alcohol nanocomposite films Marzieh Darvishzadeh Avisa 68@yahoo com November 11 2017 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 In this study the surfaces of zinc oxide nanoparticles ZnO NPs were modified by bovineserum albumin BSA as a biosafe molecule The prepared modified ZnO ZnO BSA NPswere investigated by different methods such as FT IR XRD FE SEM TEM EDX andTGA techniques The FT IR EDX and TGA analysis confirmed the grafting of BSA onthe surface of ZnO NPs Also the Morphology observations TEM analysis showed thereduction of average particle size of ZnO NPs after surface modification In the firstproject series of poly vinyl chloride PVC nanocomposites NCs containing 3 6 and 9wt of ZnO BSA NPs were prepared The resulting NCs were characterized by differentmethod such as FT IR XRD TGA UV Vis mechanical testing FE SEM TEM EDX and contact angle measurement According to the histogram diagrams from TEM images the average size of NPs was reduced in the polymer matrix In the second project poly vinyl alcohol PVA and 3 6 and 9 wt of ZnO BSA NPs were used to prepare theNCs All of the processes were performed under ultrasonic irradiation as a rapid and greenmethod The FT IR XRD TGA UV Vis mechanical testing FE SEM TEM and EDXwere used to investigate the characteristics of the prepared NCs The termal stability andUV absorption of the NCs were enhanced in compared with the pure polymer afteraddition of modified NPs to the PVA matrix Keyword Zinc oxide nanoparticles Poly vinyl chloride Bovine serum albumin Surfacemodification Poly vinyl alcohol Nanocomposite film Ultrasonic irradiation
