Ion gels have attracted a significant amount of interest as an innovative material possessing good mechanical property including stretchability and superior physicochemical characteristics including nonvolatility and high ionic conductivity. Owing to these properties, ion gels are promising solid electrolyte candidates for use in deformable and stretchable devices. Nevertheless, their low strength against mechanical stresses limits the operation stability of wearable and deformable devices. In this work, transparent, stretchable, and self-healable ion gels are prepared. These ion gels can heal themselves and restore their original shape when mechanical failure occur. We found that the healing time and mechanical and electrical properties depend on the type of ionic liquids. These results offer an effective strategy for developing stretchable and wearable device that can show outstanding tolerance to the mechanical breakdown. |
