Dimensional Engineering of Wet‐Spun MOF‐Based Woven Fabrics for Superior Electromagnetic Wave Absorption

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work fabricated MOF‐based woven absorbing fabrics with dimensional engineering via a wet spinning strategy. The absorbing fabrics achieve a reflection loss of −51.47 dB at 2.9 mm, with an effective absorption bandwidth reaching 3.54 GHz. The absorbing fabrics can be freely bent, stretched, and folded, with individual fibers exhibiting a break ...

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.
