Abstract
People could potentially mitigate heat discomfort when outdoors by combining passive radiative cooling (PRC) strategies with personal thermal management techniques. However, most current PRC materials lack wearing comfort and durability. In this study, a microarray technique is applied to fabricate the tailoring photonic-engineered textiles with intriguing PRC capability and appealing wearability. The developed radiative cooling textiles (RCTs) demonstrate appropriate air–moisture permeability, structural stability, and extended spectroscopic response with high sunlight reflectivity (91.7%) and robust heat emissivity (95.8%) through the atmospheric transparent spectral window (ATSW). In a hot outdoor cooling test, a skin simulator covered by the RCTs displays a temperature drop of approximately 4.4 °C at noon compared with cotton textiles. The evolution of our mimetic structures may provide new insights into the generation of wearable, thermal–wet comfortable, and robust textiles for exploring PRC techniques in personal thermal management applications.
