Self-Cleaning, Superhydrophobic Coatings with Improved Properties, Methods for Fabrication, and Applications Thereof

Detailed Technology Description

This invention is a self-cleaning, superhydrophobic coating characterized by extremely large contact angles (approximately 178-179 degrees) and greatly reduces the need for water as a transport medium. The fabrication methods of the invention can be scaled up for volume production and have been adapted to prepare surfaces that are superoleophobic (non-wetting for oil) or omniphobic (non-wetting for both water and oil). Applications of this technology include self-cleaning windows, wind-turbine blades, aircraft wings, wash-free automobiles, low-friction watercraft hulls, and non-stick medical device implants.
