Abstract
Textiles capable of achieving both solar heating and radiative cooling play a pivotal role in outdoor thermal management. Despite significant advancements, further improvements are necessary to enhance the optical performance and versatility. In this study, we developed a Janus textile comprising a porous poly(vinylidene fluoride-<i>co</i>-hexafluoropropylene) [P(VdF-HFP)<sub>HP</sub>] cooling layer (96.4% solar reflectance and 95.3% mid-infrared emissivity) and a Cu-nanoparticle-based heating layer (95.5% solar absorption and 89.1% mid-infrared reflectance). After 30 washing cycles, its performance remains stable. Field tests demonstrate impressive temperature differentials of +41.1 °C for heating and -4.5 °C for cooling relative to ambient conditions, thereby extending the thermal regulation range by 26.6 °C compared to conventional cotton textiles. Additionally, nanostructured surfaces impart hydrophobicity, oleophobicity, and fouling resistance. This design offers a sustainable solution with superior thermal management, stability, and self-cleaning ability for outdoor protection.
