A method of manufacturing hierarchical metallic surfaces demonstrating superhydrophobic properties is presented. The surfaces showed apparent contact angles as high as 153° and sliding angles of 10° for 50–100 μl droplets. The Cassie-like model [A. B. D. Cassie and S. Baxter, Trans. Faraday Soc. 40, 546 (1944)], considering the hierarchical topography of the relief, predicts apparent contact angles in a satisfactory agreement with the measured values.

    Impact dynamics of water droplets on superhydrophobic surfaces with different textures are known to vary dramatically, from total rebounding to complete sticking. Here we show that droplet rebounding on textured surfaces can be significantly influenced by the uniformity of the surface roughness....
