Nano-Cone Textures Generate Extremely "Robust" Water-Repellent Surfaces

Surfaces with differently shaped nanoscale textures may yield improved materials for applications in transportation, energy, and diagnostics

When it comes to designing extremely water-repellent surfaces, shape and size matter. That's the finding of a group of scientists at the U.S. Department of Energy's Brookhaven National Laboratory, who investigated the effects of differently shaped, nanoscale textures on a material's ability to force water droplets to roll off without wetting its surface. These findings and the methods used to fabricate such materials—published online October 21, 2013, in Advanced Materials—are highly relevant for a broad range of applications where water-resistance is important, including power generation and transportation.
