Abstract

Self‐healing capability offers great designability on mechanical properties of double‐network (DN) hydrogel. However, the thermodynamics understanding behind such physicochemical transitions and self‐healing behaviors are yet to be explored properly. This study describes a renormalized Flory‐Huggins...
