Self-healing and high stretchable poly(lithium acrylate)-based hydrogels for supercapacitor applications |
| 초록 |
Stretchable and self-healing properties are highly required for wearable and flexible energy storage devices such as supercapacitors. On the other hand, the drawback between high ionic conductivity and mechanical performance still becomes the typical problem to overcome. In this report, high stretchable and self-healing poly(lithium acrylate)-based hydrogels were prepared with free radical polymerization of lithium acrylate with vinyl silica nanoparticles as cross-linker and ammonium persulfate as initiator. Lithium acrylate was prepared by ion-exchanging acrylic acid with lithium hydroxide. Vinyl silica nanoparticles as cross-linkers acting as a stress buffer contribute to strengthening the polymer network under strain. Meanwhile, the self-healing ability is due to intramolecular and intermolecular hydrogen bonding of the hydrogel. Self-healing hydrogel polymer electrolytes were able to stretch up to 2000% and possessed high ionic conductivity ~10-3 S/cm at room temperature. |
