Abstract
Abstract Soft self‐healing materials are compelling candidates for stretchable devices because of their excellent compliance, extensibility, and self‐restorability. However, most existing soft self‐healing polymers suffer from crack propagation and irreversible fatigue failure due to easy breakage of their dynamic amorphous, low‐energy polymer networks. Herein, inspired by distinct structure–property relationship of biological tissues, a supramolecular interfacial assembly strategy of preparing soft self‐healing composites with unprecedented crack propagation resistance is proposed by structurally engineering preferentially aligned lamellar structures within a dynamic and superstretchable poly(urea‐ureathane)…
