Breathable and Self-Healing Photothermal Superhydrophobic Coating Featuring Exceptional Liquid Impalement Resistance and Anti-/Deicing Capabilities for Concrete Materials

= 16,000) and retains superhydrophobicity after mechanical and chemical damage. The coating also possesses self-healing capabilities via hydrogen bonds and dynamic covalent bonds, enabling recovery under sunlight, room temperature, or underwater conditions. Its anti-icing performance is evident from a delayed water freezing time (-15 °C) of 1610 s and significantly reduced ice adhesion strength (32.6 kPa). Under sunlight, the coating rapidly melts ice droplets and layers within 138 and 695 s, respectively. This work introduces a robust, breathable superhydrophobic coating with self-healing and anti/deicing capabilities, offering scalable solutions for outdoor, concrete-based architectural applications.
