Multiple‐Temperature‐Responsive Double‐ and Triple‐Network Hydrogels

摘要

Temperature-responsive hydrogels which are reversibly activated attract much attention in the field of smart materials. Herein, double- and triple-network hydrogels exhibiting dual- or triple-volume transitions upon changes of temperature are fabricated. Interestingly, the incorporation of superhydrophilic polymer network leads to a significant difference swelling or shrinkage of the multiple-network hydrogels. Applications of such hydrogels are envisioned in soft robotics or for producing programmable reactors.
