Investigation on self-healing behaviors. The modulus (G′ and G″) changes of FC hydrogel (A) and FC/FI hydrogel (B) at 1 Hz upon enhanced external strains at 25 °C (left) and an instantaneous recovery from the 1000% strain deformation (right). The damage-healing property of FC hydrogel (C) and FC/FI hydrogel (D) demonstrated by the continuous step strain (1% strain→600% strain→1% strain) measurements at a fixed time interval of 120 s at 25 °C.
