A hierarchically reversible crosslinked hydrogel has been designed with excellent mechanical properties, efficient self-healability and double-driven shape memory effect (pH, Ca2+). A soft catcher actuator was constructed, which could catch a plastic fish in Ca2+ solution.
The poly(siloxane-urethane) elastomers with microphase separation structure and Diels–Alder bonds show high healing efficiency, good mechanical property and good biocompatibility.
A unique self-healing and corrosion reporting composite polymer is successfully constructed, aiming to achieve repairing ability for wider cracks under NIR excitation and report early corrosion in graphene-based dark coatings.
