Abstract


Optical response of polymer-blend due to doping with titanium (iv) oxide nanoparticles was studied. The nanocomposites were prepared via solution-mixing technique; a two stage reaction involving the synthesis of TiO2 nanoparticles and the subsequent mixing with the host polyvinyl (alcohol-co-acetate) matrix. Initial microstructural investigation of the TiO2nanoparticles reveals an almost spherical particles (≥ 99.99% phase purity) with diameters ~ 25-40nm. Structural modifications due to TiO2 doping on the host matrix were investigated using Fourier transform infrared spectroscopy and scanning electron microscopy. Optical properties were investigated using UV-visible spectrophotometer. Optical transparencydecreased with the variation of TiO2 concentrations from 1 to 4 wt. %. The nanocomposites were found to exhibit good properties of being excellent UV filters and good visible light absorbers with an optimum in the nanocomposite with 3 wt. % of TiO2 nanofillers.
