In this study, we aim to develop photocurable materials using PDMS with excellent elasticity and stretchability, Isosorbide with UV stability and optical properties. Methacrylatoxy terminated PDMS-isosorbide was synthesized using hydroxypropyl terminated-PDMS having low molecular weight and isosorbide derived from biomass. The synthesized materials were analyzed qualitatively and quantitatively using H-NMR and FT-IR, and the photo-curing rate for the PDMS modified urethane acylate was measured via photo-DSC. Finally, Dual types of UV-IR irradiator was employed to prepare cross-linked film measure and the optical properties of the film such as transparency and pencil hardness were confirmed. |
