Aerogel Fiber: A One‐Dimensional Programmable Porous Matter for Next Thermal Management Materials

Interdisciplinary Materials, EarlyView.
Aerogel fibers are redefined as one‐dimensional programmable porous matter, where thermal transport is governed by multiscale pathway engineering. By reconstructing and decoupling transport pathways from molecular to textile scales, these systems integrate insulation, radiative cooling, and adaptive thermal regulation.

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

Macromolecular 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%.
