| Abstract |
Ceria has attracted extensive research attention due to its potential applications in a variety of research fields such as three-way automotive catalysts, solid oxide fuel cells, and optical and biomedical materials. In addition, ceria presents unique capabilities in the absorption of UV light. As UV-screen is needed as part of safe-sun practices to reduce the effects of carcinogenic and photodamaging solar UV radiation, there has been increasing research interest in employing ceria in anti-UV coating materials. However, constructing composite coating films using ceria and inorganic/polymer species with accurate control in the coating structure has remained a challenge. In this work, CeO2-x nanoparticles smaller than 10 nm in diameter showing variable band gap energy were prepared for UV-blocking composite films. Considering a large amount of surface hydroxyl groups, CeO2-x particles were dispersed in polyvinyl alcohol (PVA), a representative polymer matrix. Resulting Ceria/PVA composite films showed excellent UV-blocking performance. |
