Abstract: The present invention relates to an article having a surface coated with a nanostructured temporary super-hydrophobic film having a static contact angle with water of at least 140°, preferably exhibiting multiple length scales of roughness and comprising nanoparticles functionalized with a hydrophobic agent, wherein the functionalization of the nanoparticles with the hydrophobic agent has been performed before said nanostructured temporary super-hydrophobic film is coated on said surface. The surface of the article exhibits a static contact angle with water of at least 60° before being coated with the nanostructured temporary super-hydrophobic film. The treatment according to the invention can be used to provide an antirain function to optical articles having a hydrophobic surface.

Abstract: The present invention relates to an article having a surface coated with a nanostructured temporary super-hydrophobic film having a static contact angle with water of at least 140°, and comprising nanoparticles functionalized with a hydrophobic agent, wherein the functionalization of the nanoparticles with the hydrophobic agent has been performed before said nanostructured temporary super-hydrophobic film is coated on said surface. The surface of the article exhibits a static contact angle with water of less than 60° before being coated with the nanostructured temporary super-hydrophobic film. The treatment according to the invention can be used to provide an antirain function to optical articles having a hydrophilic surface.
