Abstract:
The invention relates to an article having a nanotextured surface with superhydrophobic properties, comprising an array of vertical tabs, preferably regular, wherein the pillar array fulfils the following conditions: the surface fraction of the pillars Øs is such that 3%≦Øs≦13%, preferably 5%≦Øs≦12%, preferably 5%≦Øs≦13%, even better 5.5%≦Øs≦13%, even better 6%≦Øs≦13%, and better still 8%≦Øs≦13%; the pitch p of the array is such that 100 nm≦p≦250 nm; the height h of the pillars is such that 100 nm≦h≦400 nm, preferably 250≦h≦400 nm, even better 300≦h≦400 nm; and the lateral surface of the pillars is inclined at most by an angle of ±20°, preferably ±10° or even better ±5°, in relation to the vertical axis of the pillars.
