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： In the method of embodiments of the invention, the metal seeded carbon allotropes are reacted in solution forming zero valent metallic nanowires at the seeded sites. A polymeric passivating reagent, which selects for anisotropic growth is also used in the reaction to facilitate nanowire formation. The resulting structure resembles a porcupine, where carbon allotropes have metallic wires of nanometer dimensions that emanate from the seed sites on the carbon allotrope. These sites are populated by nanowires having approximately the same diameter as the starting nanoparticle diameter.

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.
