Tough, adhesive, self-healing, fully physical crosslinked κ-CG-K+/pHEAA double-network ionic conductive hydrogels for wearable sensors

The development of multiple-functional conductive hydrogels with combined merits of high mechanical strength, fast self-healing, strong surface adhesion, and strain sensibility has proved to be a highly demanded, but extremely challenging task for different applications. Herein, we designed, synthesized, and characterized fully physically crosslinked double-network (DN) hydrogels of κ-carrageenan/poly(N-hydroxyethyl acrylamide) (κ-CG-K+/pHEAA DN...
