摘要： Embodiments provide ice adhesion mitigating surface coatings and methods for generating the same. Embodiments may provide anti-icing coating with at least one monomeric species exhibiting molecular flexibility. The molecular flexibility in the monomeric species may be imparted through an aliphatic or heteroaliphatic chain that may exist as a portion of the monomer backbone, as a pendant group, or as both the portion of the monomer backbone and the pendant group. In various embodiments epoxy coatings including an epoxy resin and an amine-terminated hardener may be generated. At least a portion of the amine-terminated hardener may include at least a monomeric species that exhibits molecular flexibility arising from an aliphatic chain or heteroaliphatic chain that may be within the polymer backbone and/or may persist as a pendant group.

摘要： Surface energy of a substrate is changed without the need for any template, mask, or additional coating medium applied to the substrate. At least one beam of energy directly ablates a substrate surface to form a predefined topographical pattern at the surface. Each beam of energy has a width of approximately 25 micrometers and an energy of approximately 1-500 microJoules. Features in the topographical pattern have a width of approximately 1-500 micrometers and a height of approximately 1.4-100 micrometers.

摘要： A process to modify a surface to provide reduced adhesion surface properties to mitigate insect residue adhesion. The surface may include the surface of an article including an aircraft, an automobile, a marine vessel, all-terrain vehicle, wind turbine, helmet, etc. The process includes topographically and chemically modifying the surface by applying a coating comprising a particulate matter, or by applying a coating and also topographically modifying the surface by various methods, including but not limited to, lithographic patterning, laser ablation and chemical etching, physical vapor phase deposition, chemical vapor phase deposition, crystal growth, electrochemical deposition, spin casting, and film casting.
