The icing phenomenon has become a safety hazard for the normal operation of equipment. In this work, we report strategy simply obtaining photothermal anti-icing coatings by spraying acrylic resin, polydimethylsiloxane and polydopamine modified SiO 2 particles on steel plate substrate. prepared icephobic AR/PDMS/SiO @PDA composite coating not only excellent superhydrophobicity (WCA = 162°). It also shows good anti- de-icing performances. superhydrophobic surface was able to delay freezing 614 s at −20°C, ice adhesion its 54 kPa. addition, PDA-modified endow with properties. Under irradiation simulated sunlight, rapidly reached 61°C within 3 min, droplets completely melted in 155 s. Besides, it's withstand wide range chemical attacks mechanical impacts. After 15 icing-de-icing cycles 40 sandpaper abrasions test, can still maintain remarkable ice-removal performance, demonstrating robustness stability harsh environments.
