Biocompatible Autonomic Self‐healing PVA‐TA Hydrogel with High Mechanical Strength

Front Cover: In article number 2100061 by Wei Zhang and co-workers, a high-strength PVA-TA hydrogel shows efficient self-healing performance. The strength is demonstrated through stretching the hydrogel cube. The intermediate fracture network of the hydrogel is gradually healed by the reconstruction of the H bond between the TA and PVA polymer chains.
