Abstract

A novel multifunctional supramolecular hydrogel with self-healing, shape memory and adhesive properties is successfully developed on the basis of dynamic phenylboronic acid (PBA)–catechol interactions. The reversible nature of PBA–catechol bonds renders the hydrogel with outstanding self-healing and shape memory behavior, and the mussel-inspired catechol moieties generate fascinating adhesive properties.
