A Highly Transparent and Self-healable Elastomer Based on Heterocyclic Isosorbide Oligomer With Excellent Mechanical Properties |
| 초록 |
A new heterocyclic elastomer based on isosorbide oligomer (HEIO) is synthesized and its self-healing and mechanical properties are characterized in this study. First, an isosorbide oligomer with hydroxyl groups (IO) is synthesized by reacting isosorbide and isophorone diisocyanate (IPDI). To synthesize HEIO, the blend of polyol and IO is reacted with crosslinker containing multiple isocyanate groups (Xlinker). To compare the self-healing and mechanical properties, polyol is reacted with Xlinker to prepare conventional elastomer (CE) and the blend of polyol and isosorbide is reacted with the blend of Xlinker and IPDI to prepare heterocyclic elastomer with isosorbide moieties (HEI). Interestingly, HEIO exhibits outstanding self-healing and mechanical properties compared to CE or HEI. In addition, HEIO shows better surface hardness than CE or HEI. This result is due to the strong hydrogen bonding interaction between urethane and IO, and we analyze this result through FT-IR spectroscopy. |
