dc.description.abstractA self-assembled polytetrafluoroethylene (PTFE) nanostructure is deposited on microcrystalline diamond (MCD) films, by use of physical and chemical vapor deposition in a two-step process, to produce (fully) superhydrophobic surfaces: high water contact angle (static, 165 2 deg), very low hysteresis (dynamic, ∼4 deg), and associated sliding angle (1 deg 50 150), thus combining the diamond infrared transparency and self-cleaning properties. These are interpreted in light ofWenzel and Cassie-Baxter wetting models, associated with structural microscopy of nano-micro rough PTFE/MCD surfaces, and present a promising perspective for self-cleaning infrared optics applications.en
