Organic UV absorbers are mainly used as a material for UV-cut off filters. For instance, Salicylic acid, benzophenonone, benzotriazole, and cyanoacrylate groups are known as a UV absorber. However, So far, the prepared UV-cut off films still have many challenges in heat and humidity resistant properties. So we made novel polymer films with excellent physical properties from new acrylamide monomers and conventional PMMA as a matrix material, which are blended with the UV absorbers, are prepared by a solvent casting method. Our new films absorbed UV light of 200-400 nm selectively and also showed excellent heat resistance and high optical transmittance as well as good humidity resistance. Our UV-cut off film can be applied to canopy film for aircraft, LCD protection and polarized light films etc. |
