Shape memory polymers on the basis of reversible supramolecular interactions have invoked growing research interest, but still suffer from limitations such as poor mechanical strength and finite shape memory performance. Here, we present a novel mechanical stretchable supramolecular hydrogel with triple shape memory effect at macro/micro scale. The introduction of double network concept into supramolecular shape memory hydrogels endows them with excellent mechanical properties. Design of two non-interfering supramolecular interaction systems of both dynamic phenylboronic (PBA)-diol ester bonds and the chelation of alginate with Ca2+ endue the hydrogel with outstanding triple shape memory functionalities.
