摘　　要：In recent years, researchers have paid increasing attention tothe use of radiation cooling textiles for maintaining human thermal comfort. Radiation cooling can achieve effective cooling without energy consumption by emitting heat into cold outer spacethrough an atmospheric transparent window (ATW, 8–13 lm)while reflecting solar irradiance in the solar region (0.3–2.5 lm)[1]. For example, Zeng et al. [2] reported a layered morphologyradiation-cooled textile composed of TiO2/polylactic acid and polytetrafluoroethylene. This design offers optimal mechanicalstrength, waterproofing and breathability, while enabling spectralmodulation within the 0.3–2.5 lm wavelength range and ensuringefficient radiative cooling. Yang et al. [3] developed a SiO2 microsphere-modified fabric film with shish-kebab structure. This fabricfilm exhibits high emissivity within the atmospheric window andstrong reflectivity to solar radiation, resulting in exceptional cooling properties for both indoor and outdoor applications. A key concern is that these radiation cooling textiles are typically appliedhorizontally, where they demonstrate effective cooling in sunny,unobstructed environments. However, their effectiveness may belimited in more complex real-world applications.
