摘要：

Radiative heating or cooling textiles offer a sustainable means for personal thermal management (PTM). However, textiles that can realize efficient PTM under both large indoor and outdoor temperature variations are still lacking. Herein, guided by a heat transfer model, an eco- and user-friendly bilayer textile (i-textile) integrating radiative heating and cooling is developed. The i-textile is composed of an MXene layer and a cellulose acetate (CA) layer with asymmetrical spectral characteristics. This textile provides heating when the MXene layer faces outward and cooling by wearing the textile inside out when the CA layer faces outward, thus enabling a decreased skin temperature variation range (7.3 and 6.8 degrees C lower than those when wearing cotton textiles) under large temperature variations indoors (12.6 degrees C) and outdoors (19.6 degrees C), respectively. Moreover, the i-textile presents excellent wearability (breathability and washing resistance), recyclability, and biodegradability and can save approximate to 30% of the building heating and cooling energy if widely deployed in China.
