Sprayable superhydrophobic photothermal/electrothermal anti-icing coating based on evaporation-induced surfactant flocculation self-assembly

Key Points

• To develop a superhydrophobic coating that can prevent icing and facilitate rapid de-icing.
• Utilized solvent evaporation to induce surfactant flocculation.
• Created hierarchical micro–nanostructures through self-assembly.
• Tested the coating's durability and anti-icing performance.
• Coating significantly delays icing formation.
• Demonstrated effective photothermal and electrothermal de-icing capabilities.
