Ice‐Templated Thermoresponsive Hydrogel Actuators with Fast, Low‐Hysteresis Actuation Cycles

open access: yesAdvanced Materials Interfaces, EarlyView.
The study demonstrates a synergistic fabrication concept that combines ice‐templating with in situ polymerization to produce semi‐interpenetrating network thermoresponsive hydrogels with aligned porous architectures. The thermoresponsive hydrogels exhibit rapid actuation and recovery, low hysteresis, and improved compressive strength.
