In this study, we aim to improve the properties of UV-curable polyurethane acrylate through hybrids with inorganic nanoparticles. The synthesized polyurethane acrylate was qualitatively analyzed by FT-IR and their molecular weight were observed using GPC. Organic-inorganic hybrid composites were measured for photo-curing kinetics via photo-DSC and we prepared cross-linked films by Dual types of UV-IR irradiator. Furthermore, the transmittance was observed through UV-vis, and the pencil hardness was measured to confirm the film properties. Finally we obtained transmittance of 90.7% and pencil hardness of 4H with cross-linkers.
