제목 Synthesis and characteristic of photocurable acryl-polyurethane for 3D architectures
초록  Thermoplastic UV-curable PU series were synthesized using poly(tetramethylene ether) glycol(PTMG) as polyol, methylene diphenyl diisocyanate(MDI) as isocyanate and 1,4-butandiol(1,4-BD) as chain extender based on different molecular weight of pre-polymer. Designed photocurable acryl-PU is a photo-curing system containing acrylic monomers, polyurethane, and a photoinitiator, whose properties can be manipulated by exposure to light at specific wavelengths(385~405nm). Photocurable acryl-PU will be synthesized by attaching 1,6-hexanediol diacrylate(HDDA) and used for DLP 3D printing by controlling the content ratio of photo-initiator and addition multifunctional acrylate. UV-curable PUs were evaluated by Fourier transform infrared spectroscopy (FT-IR) and gel permeation chromatography (GPC). The printed 3D structure exhibited good mechanical properties(hardness, elasticity).
