Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making an article, comprising: forming a metal coating on a glass substrate; annealing the metal coating to form balled-up metal islands; coating over the balled-up metal islands with a protective layer including sputter deposition of Ti/Au over the balled-up metal islands while leaving corner regions between the balled-up metal islands and the glass substrate open to chemical etching to selectively protect at least a portion of the balled up…
