ARTICLE HAVING A NANOTEXTURED SURFACE WITH HYDROPHOBIC PROPERTIES

摘要

An article having a nanotextured surface with hydrophobic properties, said nanotextured surface comprising an array of pillars (71) defined by a surface fraction (φs) of the pillars, a pitch (P) of the pillars and an aspect ratio (H/2R) of the pillars, wherein: —the surface fraction (s) is equal or greater to 2% and equal or less to 80%; —the pitch (P) is equal or less to 250; —the aspect ratio (H/2R) is equal or less to 2.4, where H is the height of the pillars and R is the radius of the pillars; —the pitch (P), the height (H), the radius (R) are expressed in nanometers (nm); —the nanotextured surface comprises at least partially a hydrophobic material.
