TLDR
A surface structure that mimics the water harvesting wing surface of the Namib Desert beetle is demonstrated and potential applications of such surfaces include water harvesting surfaces, controlled drug release coatings, open-air microchannel devices, and lab-on-chip devices.Abstract:
The present study demonstrates a surface structure that mimics the water harvesting wing surface of the Namib Desert beetle. Hydrophilic patterns on superhydrophobic surfaces were created with water/2-propanol solutions of a polyelectrolyte to produce surfaces with extreme hydrophobic contrast. Selective deposition of multilayer films onto the hydrophilic patterns introduces different properties to the area including superhydrophilicity. Potential applications of such surfaces include water harvesting surfaces, controlled drug release coatings, open-air microchannel devices, and lab-on-chip devices.read more

Superhydrophobic surfaces: from structural control to functional application
TL;DR: A superhydrophobic surface is a surface with a water contact angle close to or higher than 150° as discussed by the authors, and it is the combination of surface roughness and low-surface-energy modification that leads to super-hydrophobicity.

TL;DR: In this paper, the photogeneration of a highly amphiphilic (both hydrophilic and oleophilic) titanium dioxide surface was reported, and the unique character of this surface was ascribed to the microstructured composition of hydrophilicity of the phases, produced by ultraviolet irradiation.
