Project TitleSuperhydrophobic Coating Composition and Methods
Track Code2016-157
Short DescriptionPrincipal Investigators: Eric Loth, Ilker Bayer

Insect residue adhesion to moving surfaces such as on turbine blades and aircraft not only causes surface contamination problems but also increase drag on these surfaces. Insect fouling during takeoff, climb and landing can result in increased drag and fuel consumption for aircraft with laminar-flow surfaces. To address these problems, researchers at the University of Virginia, have developed a superhydrophobic films capable of maintaining negligible levels of insect residue (i.e. exoskeleton, hemolymph, and red residue) after 100 high speed (50 m/s) insect impact events. Using proprietary methods, researchers achieved specialized nanocomposite depositions on aluminum surfaces with varying surface texture, and demonstrated film performance in wind tunnel environments. Durability screening against abrasion wear, adhesion and water soaking was performed.
