- A Superhydrophobic Coating With Robust and Efficient Photothermal Anti‐Ice/Deicing Properties Was Prepared by One‐Step Spraying Liang Yin Xiaosen Wang Fapeng Zhang Yangyang Jia Yujie Liu Jiwen Wang Qiang He Journal of Applied Polymer Science ABSTRACT Currently, most superhydrophobic materials suffer from problems such as complex preparation, reliance on fluorine‐containing reagents, poor mechanical durability, and unclear photothermal anti‐icing mechanism. To address these bottlenecks, we proposed and implemented an innovative integrated strategy. Through an environmentally friendly one‐step spraying process, we combined the high adhesion of epoxy resin, the low surface energy of polydimethylsiloxane, and the photothermal and structural functions of micro‐nano SiO 2 /NiO, successfully constructing a composite coating that possesses excellent mechanical stability, long‐lasting superhydrophobicity, and efficient photothermal response. The contact angle of the coating reached 161.3°, and the sliding angle was 2°. It maintains superhydrophobicity even after 100 sandpaper abrasion cycles and 20 icing/deicing cycles, along with a highly efficient photothermal response. Anti‐icing and de‐icing tests show that at −5°C, −10°C, and −15°C, the coating delays icing by 20.5, 19.9, and 23.9 times compared to the substrate, respectively. Under 1.0 sun illumination, it melts a −15°C ice layer completely within 103 s and retains stable performance after rigorous environmental testing. This work not only provides a high‐performance anti‐icing coating but also demonstrates a universal design strategy that can synergistically enhance mechanical durability, surface superhydrophobicity, and photothermal conversion performance. It offers an indispensable solution for the surface protection of critical equipment in extreme environments. 10.1002/app.70613 http://onlinelibrary.wiley.com/termsAndConditions#vor
