Superhydrophobic surfaces are materials that exhibit extreme water repellency, characterized by contact angles greater than 150 degrees. These surfaces are created by combining nanostructures with low-surface-energy materials. The roughness at the nanoscale traps air, causing water droplets to bead up and roll off, taking any contaminants with them. This property is advantageous for anti-icing as it prevents water from freezing on the surface.
