Tough and Fast Thermoresponsive Hydrogel Soft Actuators
Advanced Materials Technologies, EarlyView.This work develops tough, fast‐responding thermoresponsive double‐network hydrogels that combine excellent mechanical strength with rapid actuation. Composed of PNIPAm and ether‐based polyurethane, the hydrogels achieve ≈8 MPa compressive stress and ≈30% contractile stroke within 2 min at 50 °C, enabling temperature‐responsive fluid flow switching for ...
