This paper reviews the current knowledge on superhydrophobic and icephobic coatings and, by using an ideal super-hydrophobic surfaces patterned with identical cylindrical flat top posts forming a square network with constant periodicity, models are proposed to explain super-hydrophobic coating wear and ice adhesion on super-hydrophobic coatings. The models demonstrate: that super-hydrophobic and icephobic coatings based on the Cassie-Baxter state are more suitable for aircraft surfaces than coatings based on the Wenzel state; with the Cassie-Baxter state, erosion resistance can be improved by increasing the post height however their ability to reduce ice adhesion when use as an icephobic coatings is limited. The model shows that the ice adhesion reduction factor (IARF) of a super-hydrophobic coating is based on the IARF of hydrophobic material and on the pattern of the surface. As an example, patterning the surface of hydrophobic material with water contact angle (WCA) of 125 ° can bring the hydrophobic material to super-hydrophobicity with a WCA of 165° and increase the IARF by a factor up to 14. It was observed from experiment that no ice-ridge forms when the AIPS is used when combined with a super-hydrophobic coating in running wet mode. The reason is not well understood but water shedding is assumed to be the main driver. A model is proposed which explains how water can be shed from super-hydrophobic surfaces. Due to the sphericity of the bead resting on super-hydrophobic material and non-uniform velocity profile over the wing surface, beads roll on the surface. The rolling bead creates lift which lifts off the bead from the surface. The models proposed in this paper can help to define super-hydrophobic coating requirements for aerospace. However erosion resistance and process industrialization are probably the biggest challenge for manufacturers and designers of coatings.
