The development of Poly(N‐vinylcaprolactam) (PNVCL)‐based hydrogels for additive manufacturing remains challenging due to the difficulty of simultaneously achieving printability and enhanced thermoresponsive performance. Herein, chemically crosslinked P(NVCL‐DVA) organohydrogels (DVA, 3,9‐divinyl‐2,4,8,10‐tetraoxaspiro[5.5]undecane) were prepared using diethylene glycol (DEG) as a cosolvent with water and fabricated by digital light processing (DLP) 3D printing, followed by solvent exchange with water. The influence of formulation parameters, particularly DEG content, on network formation and thermoresponsive behavior was systematically investigated. The optimized hydrogels exhibited interconnected porous structures associated with high water uptake, enhanced deswelling amplitude, and rapid deswelling and reswelling kinetics. Collectively, these findings establish an effective formulation strategy that expands the potential of PNVCL‐based materials for DLP 3D printing.
Thermoresponsive hybrid poly(N‐isopropylacrylamide) (PNIPAAm) hydrogels physically cross‐linked with Laponite RD (Lap) platelets and chemically cross‐linked PNIPAAm hydrogels formed within polyvinyl formal (PVF) sponges were synthesized. The hydrogel systems were loaded with the bacteriostatic agent sulfacetamide sod...

As a nanoscale derivative of poly(p‐phenylene terephthalamide) (PPTA), para‐aramid nanofibers (ANFs) largely retain the exceptional mechanical and thermal stability of bulk PPTA fibers while offering high specific surface area, abundant surface active sites, and remarkable nanoscale effects. These advantages make ANF...
