Volume Transition of PNIPAM in a Nonionic Surfactant Hexagonal Mesophase
We investigate the volume transition of a thermoresponsive polymer, poly(N-isopropylacrylamide), PNIPAM, in the presence of an aqueous solution of nonionic surfactant, C12E9.

By analyzing the thermal‐mechanical properties and molecular‐scale interactions in polyacrylamide (PAAM) hydrogels, this research demonstrates a rubber‐glass‐crystal phase transition under the combined stimuli of temperature and moisture. Because of these hybrid phase transitions, PAAM hydrogels exhibit shape memory behavior in thermal and moist ...

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