【 摘 要 】

tsHighly 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.
