摘要：
Aerogels have been considered as super thermal insulators since their invention in 1931. The successful adoption of aerogels, which are made by replacing the liquid in a gel with gas while maintaining a stable network, in NASA vehicles such as the Mars rover has inspired the use of aerogels in personal warming. But applications of aerogels in textiles have been limited by their insufficient moisture permeability. Aerogel fibers are being developed to address the trade-off between thermal insulation and moisture permeability. However, aerogel fibers presently lack the strength and flexibility necessary to allow weaving or knitting into a wearable fabric. On page 1379 of this issue, Wu et al. (1) report a feasible strategy to construct bioinspired knittable aerogel fibers with superb thermal insulation and mechanical robustness, which allows weaving into fabric with air permeability. This could instigate the development of advanced thermal textiles for personal warming.
