Photon-engineered radiative cooling textiles
WebApr 21, 2024 · Combined with the non-absorbent characteristic of PE fibers, engineered PE textiles also exhibit quick-drying performance over polyester and cotton textiles. Cooling performance shows that PE textiles have rapid waterfront propagation and simultaneous fast evaporation, which can reduce the temperature by more than 5°C in less than 10 min … WebMar 1, 2024 · An optimized bio-inspired radiative cooler showed the emissivity (8–13 μm) of 0.98. • The radiative cooler was measured to absorb 20–25 W/m 2 of solar irradiance.. The net cooling power of the radiative cooler was estimated to be 144 W/m 2.. In Hong Kong's sub-tropical climate, the cooler remained 6.2 °C below the ambient.
