Abstract
Radiative thermal management textile regulates reflectivity, emissivity, and transmissivity to achieve different thermal functions without any electrical or chemical energy consumption. Despite significant advances, achieving effective radiative cooling in high humidity weather and improving textile resistance to temperature shocks remain challenges. Here, we exploit a novel trimode all-weather personal thermal management textile (TAWT) that combines radiative cooling, solar heating, heat storage and release of phase change. High solar reflectance of 96.6% and Mid-infrared emittance of 93.2% of TAWT in cooling mode generate a temperature drop of 13.1℃ and 9.2℃ compared to bare skin and traditional textile. The unique solar absorptivity of 82.0% and low infrared emissivity of 67.8% in heating mode prevents overcooling by 10.9℃ compared with bare skin. The large heat enthalpy density of 81.1 J/g created an additional temperature drop of 3.9℃ in high humidity weather, which effectively makes up for the shortage of radiative cooling capacity. Meanwhile, the heat storage and release of phase change enhance the resistance of the human body to temperature shocks. In addition to thermal management capabilities, TAWT also exhibits favourable wearability. Given these attractive advantages, TAWT would offer advance insight for the development of functional textiles.
