Abstract

La présente invention a pour objet une lame caoutchouc d'essuyage (10) pour un essuie-glace qui comporte un corps de base de lame caoutchouc d'essuyage (1). Pour améliorer ses propriétés de répulsion de l'eau et sa stabilité en particulier sous l'action d'une force de contact verticale, une partie du corps de base de la lame caoutchouc d'essuyage (1) comporte une structuration de surface avec des reliefs (2) à l'échelle micrométrique, une couche fortement hydrophobe (3) étant formée entre les reliefs (2), et les reliefs (2) dépassant de la couche fortement hydrophobe (3) formée entre ces reliefs. La présente invention a en outre pour objet une raclette d'essuyage comportant une telle lame caoutchouc d'essuyage ainsi qu'un procédé d'obtention d'une lame caoutchouc d'essuyage.
