The lotus leaf shows superhydrophobicity and extreme nonsticking properties due to the two-level roughness features of its surface in addition to the low surface energy. In the thin film of vertically aligned treelike carbon nanostructures, each nanostructure is a multiwalled carbon nanotube aligned vertically to the plane of the substrate with carbon films attached to the nanotubelike branches, giving the overall treelike appearance. These nanostructures also have two-degree roughness due to their unique geometry, which makes the wettability of the material an interesting property to study. The change in hydrophobicity of the material as a function of the deposition time is studied to understand the mutual dependence of the geometry of the nanostructures and the hydrophobicity of the film. The material exhibits superhydrophobicity, showing a static water contact angle as high as 165? for certain deposition conditions with extreme nonsticking properties. © 2019 American Physical Society.
