Surface, Temperature and Optical Properties Pd-TiO₂Doped PVA Nanocomposite

Abstract

The effect of Pd-TiO2 nanoparticle doping on structural, optical and thermal properties of the PVA polymer has been investigated using FTIR, UV-Visible, TGA and FESEM analysis. nanosized Pd-TiO2 particles were synthesized using standard method. Pure and Pd-TiO2/PVA nanocomposite films were prepared using solution casting technique. The FTIR study confirmed that the Pd-TiO2 nanoparticles interacts with the OH group of PVA polymer and forms the complex. The presence of these complexes affects the optical and thermal properties the composite. The change in the optical properties was studied using UV-Vis absorption method. The effect of doping on the thermal properties was studied using TGA method and the modified surface morphology using FESEM.
