Colored Woven Cloth‐Based Textile for Passive Radiative Heating

Abstract Personal thermal management is attracting growing attention due to the aggravation of climate anomalies and the increasing emphasis on physical health. Passive radiative heating textiles offer a promising solution to improve thermal comfort without energy consumption; however, using woven cloth to achieve passive heating while still exhibiting an aesthetic appearance remains a problem. Here, a colored textile based on woven cloth that features superior passive radiative heating capability without sacrificing aesthetics is demonstrated. By coating infrared transparent inorganic nanoparticles on MXene‐decorated cotton, the textile achieves selectively visible reflectance for desired color, high near‐infrared absorptivity, and low mid‐infrared emissivity for passive heating management, as well as uniformly distributed nanopores for wearability. Thermal tests on simulated skin and real human bodies show considerable temperature increases compared to pure cottons. Owing to its easy manufacturing process and remarkable spectral engineering capability, this textile can be further applied to energy conservation and multi‐spectral camouflage.
