An example from nature : Analogous to the surface structure of the lotus leaf, the micro‐ and nanostructured rough surfaces of a teflon‐coated mesh film engender it with both super‐hydrophobic and super‐oleophilic properties. The result is a variable film with contact angles of ≈150° for water and almost 0° for diesel oil, which makes it an ideal tool for the separation of oil and water (see figure).
