In this study, transparent, colorless polymer composites of polyvinyl alcohol (PVA) and tungstophosphoric acid (PWA) with high refractive indices were developed. The composite films were prepared on glass, using a facile spin-coating method, from an aqueous mixture of PVA and PWA without surfactants. The optical properties of the obtained films were investigated using an ultraviolet-visible absorption spectrometer and a prism coupler. Resultant PVA/PWA (90 wt%) composite films exhibited high transparency (90% T) in the visible region and had a high refractive index (n = 1.72). These PVA/PWA films were also compared to corresponding composite films of PVA and titanium oxide (TiO2). (C) 2017 Elsevier B.V. All rights reserved.
