A Highly Self-Healable Heterocyclic Elastomer With Outstanding Optical and Mechanical Properties for Flexible Displays |
| 초록 |
A highly self-healable heterocyclic elastomer (ShHCE) is synthesized and its self-healing and mechanical properties are examined in this study. An acrylate-based heterocyclic polyol is synthesized from a heterocyclic acrylate and 4 different kinds of acrylic monomers and then reacted with a cross-linker containing multiple isocyanate groups to prepare ShHCE. In this work, we study the effect of the amount of heterocyclic groups on the healing kinetics and healing efficiency. From the results of single and nanoscratch tests, the elastomer based on heterocyclic moieties shows better self-healing performances and mechanical properties than conventional elastomer with no heterocyclic groups. This is primarily due to the unique supramolecular structure resulting from enhanced hydrogen bonding interaction between urethane groups and heterocyclic groups. A model for the self-healing mechanism is derived by analyzing Fourier-transform infrared spectra. |
