摘要
Highly porous aerogel with longitudinally aligned channels and whisker-like ligaments is constructed by solvent-assisted unidirectional freezing. The thermal insulation and solar reflection capabilities of the composite aerogel reach a state-of-the-art level. The composite aerogel capable of infrared stealth and temperature preservation presents great potential for application in energy-saving buildings.
