Effect of TiO2 Nanoparticles on Structural and Optical Properties of Poly pyrrole, Poly vinyl alcohol Polymer Blend Thin Films

Thin films of (Poly Pyrrole - Poly Vinyl Alcohol) PPY-PVA polymer blend doped with different concentration of TiO2 nano particles were prepared via oxidative chemical polymerization technique (in-situ). The properties (Structural & Optical) of these thin films were studied by XRD, FTIR, SEM and...

description Thin films of (Poly Pyrrole - Poly Vinyl Alcohol) PPY-PVA polymer blend doped with different concentration of TiO2 nano particles were prepared via oxidative chemical polymerization technique (in-situ). The properties (Structural & Optical) of these thin films were studied by XRD, FTIR, SEM and UV spectroscopic techniques. The optical band gap values of TiO2 doped polymer blend were calculated by UV spectroscopic studies, and also noticed that obtained band gap values were decreased with increase in the concentration of TiO2 nano particles. XRD and FTIR results support the polymer blend formation, and dispersion of TiO2 nano particles in the polymer blend. The modification in surface morphology of polymer blend is due to presence of TiO2 nano particles which was confirmed by SEM results.
