Abstract

Artificially structured surfaces possessing hierarchical micro- and nanostructures are prepared with a one-step production process. These surfaces, exhibiting controlled dual-scale roughness, qualitatively and quantitatively mimic both the structure and the water repellent characteristics of the natural Lotus leaf and constitute one of the most water-repellent artificial surfaces ever reported.
