Abstract

An ultraviolet (UV)-curable nano cerium oxide (CeO2) coating with enhanced blue light and UV shielding properties, prepared using an ultrasonic blending method, is presented. This study systematically investigated the optimal synthesis conditions for nano CeO2, as well as the effects of UV intensity and CeO2 concentration on the curing kinetics and blue/UV light shielding performance of the UV-curable nanocomposite. The results indicate that the synthesized nano CeO2 exhibited improved mechanical properties and reduced agglomeration compared to commercially available CeO2. Furthermore, the UV-cured PUA/CeO2 composite demonstrated superior reflection and scattering capabilities for both blue and UV light compared with composites containing commercial CeO2 at equivalent additive concentrations. These findings highlight the potential of the proposed nanocoating for applications requiring robust UV and blue light shielding performance. When the nano CeO2 content is 4%, the shielding rates of the coating for UV and blue light are approximately 40% and 34%, respectively. The cured composites have excellent mechanical properties. Its pencil hardness can reach 4H, adhesion, 4B, flexibility, 5 and has good abrasion resistance. This indicates its potential for industrial applications. The UV cured nano-coating is expected to be used in the field of electronic products, such as display screen protective layers for mobile phones, ipad, tablets, etc., to reduce the damage to human vision caused by long-term use of these products.

Keywords: UV-curable coating; nano CeO2; UV, blue light and shielding
