Abstract Ice accretion causes significant energy losses and safety risks across various sectors. Recent research shows that liquid‐like surfaces (LLS) with ice‐shedding properties can be created by covalently attaching linear polymer chains onto smooth substrates sufficient hydroxyl group densities. To expand the substrate scope for LLS, a novel system using non‐halogenated organosilanes attached to commercial epoxy‐silicon ( EpSi ) coating is proposed. The layer, easily applied simple methods, serves as intermediate layer R = 0.94 nm q 0.76 nm). Air plasma activation increases density on , enabling LLS formation via immersion in an organosilane solution. resulting exhibits low contact angle hysteresis (<10°), sliding (SA < 14°), ice adhesion strength τ 20 kPa). Effective generated regardless of type, thickness, or application method. retains its slippery after exposure harsh conditions, including icing/deicing cycles, organic solvents, acidic environment. It also highly transparent T ave 84.5%, t 500 µm) self‐cleaning anti‐staining capabilities. This methodology broadens offering sustainable solution challenges.

Ice accumulation on wind turbine blades poses a significant challenge to performance and safety, these issues have led extensive research developing effective anti-icing methods. Polymer-based icephobic coatings emerged as promising solutions, given their passive nature low energy requirements. However, is complex task. In addition properties, factors such mechanical strength, durability, resistance UV, weathering, rain erosion must be carefully considered ensure withstand the harsh conditions faced by turbines. The main in coating engineering mastering chemistry behind coatings, it determines performance. This review provides comprehensive analysis of suitability current for applications, emphasizing alignment with present industrial standards underlying chemistry. Unlike previous works, which primarily focus aspects icephobicity, this highlights critical yet underexplored role chemical composition explores recent advancements polymer-based coatings. Additionally, earlier studies largely neglect specific required applications By demonstrating that no existing fully meets all necessary criteria, work underscores both urgency improved durability pressing need establish robust, application-specific also combines insights from cutting-edge are coupled active de-icing methods, known hybrid approach. organizing summarizing innovations, aims accelerate development reliable efficient systems pave way cleaner more sustainable future.

Abstract The photothermal superhydrophobic coating has garnered considerable attention owing to its captivating and promising deicing applications in an eco‐friendly efficient way. However, designing active‐deicing nanocoating with both mechanical stability, superhydrophobicity, performance from molecular structure remains a challenge. Herein, robust epoxy (EP)&polysiloxane (PS) (EP&PS‐PSC) is constructed by combining hydrophilic EP hydrophobic PS along graphene nanosheets via phase separation swelling treatment strategy. Notably, polar lower volume shrinkage can effectively inhibit swelling‐type polymers achieve subsequent micro‐/nanostructures construction. Besides, the also provide strong interaction interactions between micro‐/nanostructures. While non‐polar liquid silicon rubber provides low surface energy for achieving composite Furthermore, as‐prepared EP&PS‐PSC exhibits exceptional stability (e.g., 100 cycled sandpaper linear abrasion g load) WCA of 154.9° ± 1.2° WSA 4.8° 1.3°, which beneficial improve physicochemical performance. combination long‐term superhydrophobicity capability results maximum temperature 59.4 °C being achieved within 400 s under standard sunlight. This work offers novel approach mass production practical application active field.

Asymmetric structures have exhibited significant advantages in regulating wetting behavior. Nevertheless, the influence of this unique structural feature on anti-icing performance remains to be further explored. In work, static/dynamic is investigated asymmetric superhydrophobic fabricated by micro-milling combined with electrodeposition. Notably, although reduction degree asymmetry increases droplet adhesion force augmenting solid-liquid interface, can still enable bounce off surface through horizontal Laplace generated contact angle difference between two sides droplet. On basis, a dynamic behavior criterion for detach from established at low temperatures. Molecular dynamics simulation indicates that structure reduce icing probability precursor film inhibiting nucleation and growth process water molecules, decreasing liquid-ice reducing under Generally, specific inhibition characteristics increase driving during retraction stage enhancing force, effectively improving non-wetting even -40 °C.
