In this study, transparent and flexible PUAs were polymerized using PDMS with excellent elasticity, elasticity, and biocompatibility, and PTMG of low cost, high elongation, and flexibility. We successfully synthesized PUAs and biomass-derived isosorbide methacrylate with excellent optical properties for DLP 3D printer to manufacture a 3D structure. Before we applied to DLP printer, synthesized materials were subjected to qualitative and quantitative analysis using FT-IR and 1H-NMR respectively. Especially we confirmed that PUAs have a similar molecular weight of 20,000g/mol through high temperature GPC. |
