Reed-inspired dual-siloxane engineering of cellulose nanofibril/alginate aerogels for wet-dry-tolerant thermal insulation.
Cellulose-based aerogels are promising sustainable thermal insulators, but their hydrophilic skeletons absorb moisture, causing capillary-shrinkage-induced collapse and insulation loss. Meanwhile, rigid hydrogen-bonded or ionically cross-linked networks fatigue under cyclic deformation. Inspired by reed structures, whi...
