Ice-phobic surface

Icephobic surface means a surface that repels ice. The aim is to either lessen ice accretion, or lower ice adhesion strength.
The higher the icephobicity is, the more suitable the surface is for anti-icing. When making icephobic surfaces, three aspects should be considered: lowering ice adhesion, decreasing ice nucleation and slowing freezing. Icephobicity can also be increased with surface topography, like biomimetic surfaces that also are hydrophobic. Icephobic coatings in use are often polymers.
