A radiative cooling nanofabric was designed to reflect incoming solar light, exhibit strong emissivity, and simultaneously provide moisture-wicking properties, making it suitable for personal thermal management in hot outdoor environments. We developed a nanofabric with fibrous sphere architecture, consisting of polyacrylonitrile-SiO2 and poly (vinylidene fluoride-co-hexafluoropropylene)-TiO2-Al2O3 as hydrophilic and hydrophobic layers, complementing high solar reflectivity and directional water transport as well as promising …
