Epoxy-based coatings with controlled surface chemical and topographical modifications were evaluated for mitigation of insect residue and in-flight ice adhesion. In flight testing, some surface properties (surface chemistry and topography) reduced the number of insect residues and the amount of material left behind. However, the surface properties to mitigate ice adhesion were different. Du-rotaxis-like interactions present on a low roughness surface may be a viable approach to mitigate insect residue and ice adhesion using a single coating.
