A Highly Self-Healable Heterocyclic Elastomer Based on Isosorbide Oligomer With Excellent Surface Hardness |
| 초록 |
A new heterocyclic elastomer based on isosorbide oligomer (HEIO) is synthesized and its self-healing and mechanical properties are studied. To prepare HEIO, an isosorbide oligomer with hydroxyl groups at both ends is synthesized and reacted with acrylate-based polyol (aPo) and crosslinker with multiple isocyanate groups (Xlinker). To compare the self-healing and mechanical properties, aPo is reacted with Xlinker to prepare conventional elastomer (CE) and isosorbide and aPo are reacted with Xlinker to generate heterocyclic elastomer with randomly distributed isosorbide moiety (HEI). Interestingly, HEIO exhibits outstanding self-healing efficiency compared to CE without isosorbide moiety. In addition, HEIO shows more enhanced surface hardness than CE or HEI. These results demonstrate that the conventional elastomer can achieve both excellent self-healability and mechanical surface properties by introducing isosorbide oligomer where heterocyclic isosorbide compounds are connected. |
