Self-Healable, Recyclable, and Ultrastrong Adhesive Ionogel for Multifunctional Strain Sensor

Flexible electronic materials have aroused significant interest due to the need for flexible electronics in a variety of applications. However, several obstacles such as low mechanical properties, interfacial adhesion problems, and nonreusability hinder their rapid development. Here, an ionogel was developed by a one-step photopolymerization of an ionic liquid (IL) with the C═C bond of 1-vinyl-3-butylimidazolium tetrafluoroborate in another...
