Even though the huge potential in significantly decreasing the energy consumption for cooling buildings and the human body is presented by radiative cooling technology, there is still a long way to realize its real-commercial application, considering comprehensive performances, such as safety, comfort, longevity, and production cost. Inspired by the biological micro-nano structures of Cyphochilus, we develop a one-step, large-scale, and low commercial-cost method to prepare multifunctional composite textiles, with effective cooling, fire safety, and directional water transportation. The high emissivity (96.8 %) in the atmospheric window and high reflectivity (97.1 %) in the solar waveband are successfully achieved. When exposed to direct sunlight, composite textiles can achieve up to 5 °C below commercial textiles at a solar intensity of 750 W•m −2 . Besides, the directional water transportation and the excellent mechanical strength further improve the practical application. This work proposes a radiatively cooled composite textile to achieve personal thermal management and fire protection to meet the needs of specialty garments such as firefighting suits.
