Abstract

Superhydrophobic surfaces with contact angles between 173° and 180° can be produced simply by spontaneous deposition of a textured gold or silver coating layer, followed by a self-assembled monolayer of polyfluoroalkyl thiol. Objects of any size or shape may be coated. For example, the metal “pond skater” (photo) stands on superhydrophobic copper legs.
