Ice accumulation is a persistent problem in high-altitude or low-temperature environments, resulting the abnormal operation of equipment and even fatal accidents. As such, various strategies for removing (de-icing) preventing (anti-icing) ice from outdoor have been proposed. In this study, simple photothermal superhydrophobic coating system was developed by combining hydrophilic/hydrophobic silica agglomerates, polydimethylsiloxane matrix, organic dyes (diaminonaphthyl fluorine, DANF) to prevent loss superhydrophobicity during accumulation. The prepared spray-coating method exhibited excellent with uniform water contact angle ∼165° sliding ∼3.5° over large area. Sunlight-responsive DANF dye dispersion stability common resins higher conversion efficiency than inorganic dyes, can increase surface temperature ∼30 °C an extreme freezing environment (−20 °C) under near-infrared laser irradiation (808 nm, ∼1 sun). Therefore, solar irradiation, on be delayed (anti-icing). Even after formation, initial recovered through thermal evaporation molecules trapped within micropillars (de-icing). proposed coatings photoinduced heating area sunlight, self-cleaning performance, adaptability substrates, indicating their expected applicability types performance due

Abstract Passive deicing technologies achieved by dynamic superhydrophobic surfaces and slippery substances contribute to widely used anti‐icing. However, the constant status of microstructures cannot cater changing environment, meanwhile, energy barrier needs be improved. Here, a standing‐fiber surface with three‐level is fabricated electrical flocking technology, which directly utilizes wind field assist The has low ice adhesion 2.7 kPa, high water contact angle 171.1°, long icing delay time 859 s under −30 °C. superhydrophobicity contributes excellent repellency droplet retracting bouncing distance 3.53 3.75 mm. In at 9 ms −1 , inclined theoretically accelerates motion 1.5 times compared lying‐fiber surface. difference in thermal conductivity between front back sides makes it an ideal candidate for designing anti‐icing, deicing, insulation clothes.
