Abstract
Systems, techniques and applications for nanoscale coating structures and materials that are superhydrophobic with a water contact angle greater than about 140° or 160° and/or superoleophobic with an oil contact angle greater than about 140° or 160°. The nanostructured coatings can include Si or metallic, ceramic or polymeric nanowires that may have a re-entrant or mushroom-like tip geometry. The nanowired coatings can be used in various self-cleaning applications ranging from glass windows for high-rise buildings and non-wash automobiles to pipeline inner surface coatings and surface coatings for biomedical implants.
