Abstract
Abstract Self‐healing materials behave with irreplaceable advantages in biomimetic intelligent robots (BIR) for avoiding or reducing safety hazards and economic losses from accidental damage during service. However, the self‐healing ability is unreservedly lost and even becomes rigid and fragile in the cryogenic environment where BIR are precisely needed. Here, the authors report a versatile ionic hydrogel with fast self‐healing ability, ultra‐stretchability, and stable conductivity, even at −80 °C. The hydrogel is systematically optimized to improve a hydrogen‐bonded network nanostructure, coordinated achieving a quick self‐healing ability within 10 min, large deformation tolerance of over 7000%, superior…
