| 논문초록 | Two types of UV‐curable polyurethane acrylate (PUA) prepolymers were synthesized by using toluene‐2,4‐diisocyanate (TDI) or isophorone diisocyanate (IPDI) with polycaprolactone diol (PCLD). The prepolymers subsequently reacted with 2- hydroxyethyl methacrylate. The structure of PUA was characterized by Fourier transform infrared spectroscopy. The PUA mixed with trimethylol propane triacrylate (TMPTA) and 1,6-hexanediol diacrylate (HDDA). The mechanical properties, thermal properties, and optical properties of the cured mixtures film were investigated. In comparison with PUA mixture film using PCLD–IPDI (P-I film), PUA mixture film with PCLD-TDI (P-T film) showed relatively high thermal decomposition temperatures and tensile strength. Also, we confirmed an increase in the yellowness index of P-T film in comparison with one P-I film. |
