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.
