Ultrahydrophobic Coatings for Corrosion Protection

Bryan E. Koene, Luna Innovations Incorporated; C. Jeffery Brinker, Sandia National Laboratories

The development of ultrahydrophobic coatings that are safe, economic, and applicable to a variety of different materials will result in significant savings due to the prevention of water-caused damage such as corrosion and reduced maintenance requirements. Recent studies of naturally occurring ultrahydrophobic properties in plants have identified the so-called "Lotus Effect", where super-water repellent properties are conferred by micro and nanostructures present on the plant leaf.  Similar types of structural features can be synthetically produced using a variety of means to modulate surface energy and roughness. We will discuss the properties of ultrahydrophobic coatings, and provide examples of how their application can result in corrosion prevention.
