Abstract In extreme cold and dynamic environments, active passive ice‐phobic coatings face performance degradation due to surface issues low photoelectric‐thermal conversion. Photothermal solid‐like slippery coating (PSSC) is developed using the “yin‐yang associative elements” idea. By combining low‐thermal‐conductivity microspheres, nano‐porous aerogels, silicone oil, epoxy, PSSC forms a micro‐nano‐nano light‐trapping structure surface. It has 2.6° water sliding angle, 9.2 kPa ice adhesion, an icing delay 79.5 times that of bare aluminium (Al). Moreover, also exhibits excellent corrosion resistance environmental durability. After 30 days ultraviolet (UV) irradiation saltwater immersion, angle increases minimally. Its boosts photothermal performance, heating 148 °C in 20 s under 1 sun irradiation. At –20 °C, it melts fast with Notably, at 80% Relative Humidity (RH), 80 rpm min −1 defrosting test, defrosts 180 s. The can achieve rapid removal within −30 °C. PSSC's ability environments offers new thoughts for advanced development.
