Solvent‐Tuned DLP 3D‐Printed PNVCL Hydrogels With Enhanced Thermoresponse

open access: yesMacromolecular Rapid Communications, EarlyView.
DLP 3D printing of PNVCL hydrogels remains challenging due to a trade‐off between printability and thermoresponsive performance. Here, DEG‐tuned P(NVCL‐DVA) organohydrogels were successfully 3D‐printed and subsequently solvent‐exchanged with water. The optimized hydrogels exhibited interconnected porous structures, high water uptake and rapid thermo ...

Thermoresponsive Gel‐Yarn Composites Enable Low‐Temperature Tensile Actuation in Twisted and Coiled Polymer Artificial Muscles

open access: yesMacromolecular Rapid Communications, EarlyView.
Thermoresponsive gel–yarn composites integrate poly(MAA‐co‐OEGMA) hydrogels with twisted and coiled polyester yarns to enable reversible tensile actuation between 25°C and 50°C. Hydrogel swelling and deswelling generate internal stresses that drive lengthwise actuation, achieving isotonic strains up to 39%.
