Radiative cooling technology has major benefits for energy-free thermoregulation since it can chill items without using any energy. However, the efficacy of radiative materials is hampered by outdoor pollution as well a number safety issues involved in practical applications, particular, fire hazard polymer-based materials. Here, porous composite film was created and manufactured that flame-retardant, cooling, superhydrophobic. The average infrared emissivity reached 97.2% with an solar reflectance up to 98.4%.

Daytime radiative cooling dissipates heat from surfaces by reflecting sunlight and emitting infrared radiation to outer space, featuring zero-energy consumption. Wood-based coolers have received more attention due their high emissivity, sustainability, low cost. However, they often degrade under ultraviolet (UV) exposure, resulting in a poor efficiency. Herein, inspired the structure-functionality relationship Saharan silver ants, an outdoor durable wood (DCW) is developed that achieves excellent comprehensive performance via assembly of photonic structure Mica@TiO2 on delignified wood, including both solar reflectance (0.958), emittance (0.95), mechanical strength (47 MPa), UV resistance. The unique can prevent breaking C-O-C skeleton direct sunlight; daytime efficiency DCW maintain 4.5 °C after 720 h exposure. This work paves way for development materials energy savings.
