文摘

High refractive index (high-n) PVA composites were prepared without surfactants. Tungstophosphoric acid (PWA) was employed as a high-n nanomaterial as well as TiO2. The PVA/PWA films were colorless, transparent, and exhibited n of ca. 1.7. The n value of the PVA/PWA films was equivalent to that of the PVA/TiO2 films.
