Durable Ceramicization‐Induced Uncoated Superhydrophobic Surfaces for Anti‐Icing Propeller Edges

Abstract The chemical and mechanical instability of conventional coated decorative superhydrophobic anti‐icing surfaces on propeller leading edges has been a major limitation for practical applications. Here, a self‐starting, uncoated, and ultra‐durable superhydrophobic anti‐icing surface fabricated on silicone rubber via laser‐induced ceramization microstructuring is demonstrated. The laser‐processed surface achieves a water contact angle of 168° and a sliding angle of 0.3°, exhibiting a static ice delay time of 2880 s at −25 °C and a dynamic anti‐icing duration of 132 s in wind tunnel tests. Remarkably, after mechanical abrasion (>600 s), chemical corrosion (>240 h), and 30 ice‐adhesion cycles, the surface maintains stable superhydrophobicity and anti‐icing performance. These properties are ascribed to the synergistic effect of laser‐generated microstructures and surface ceramization, which enhance environmental durability and deicing efficiency. This work provides a viable strategy for achieving long‐term anti‐icing performance on equipment surfaces under extreme conditions.
