A highly self-healable polyurethane based on sustainable isosorbide for flexible electronic displays |
| 초록 |
A highly self-healable polyurethane is synthesized based on sustainable isosorbide that is a heterocyclic compound and its self-healing and mechanical properties are examined in this study. The isosorbide-based polyurethane (IPU) has outstanding self-healing ability compared with conventional polyurethane (CPU). This is attributed to the unique supramolecular networks resulting from the strong intermolecular interactions between urethane groups in polyurethane and heterocyclic groups in isosorbide. FT-IR spectroscopy is applied to confirm the effective self-healing mechanism of IPU and a universal testing machine is used to compare the mechanical properties of IPU and CPU before and after the self-healing processes, respectively. Since the self-healing material containing isosorbide exhibits excellent self-healing and mechanical properties, this work provides an avenue for the fabrication of functional self-healing coating materials for flexible electronic displays. |
