Title (EN) DURABLE SUPERHYDROPHOBIC SURFACES
(FR) SURFACES DURABLES SUPERHYDROPHOBES
Abstract:
(EN) A superhydrophobic appliance is an elastomeric material with a surface having a multiplicity of re-entrant features. The elastomeric material can be a polydimethylsiloxane network. The superhydrophobic appliance can be formed by infusing a portion of a polydimethylsiloxane polymeric precursor partially into the pores of a porous membrane, curing to the polymeric network, and separating the membrane from the appliance to expose the superhydrophobic surface. The superhydrophobic surface can be subsequently modified to form a fluorinated surface that is oleophobic or superoleophobic in addition to being superhydrophobic.
(FR) La présente invention concerne un appareil superhydrophobe qui est un matériau élastomère avec une surface ayant une multitude de caractéristiques rentrantes. Le matériau élastomère peut être un réseau de polydiméthylsiloxane. L'appareil superhydrophobe peut être formé en laissant s'infiltrer partiellement une partie de polydiméthylsiloxane précurseur polymère dans les pores d'une membrane poreuse, en laissant durcir le réseau polymère et en séparant la membrane de l'appareil afin d'exposer la surface superhydrophobe. La surface superhydrophobe peut être ensuite modifiée pour former une surface fluorée qui est oléophobe ou superoléophobe en plus d'être superhydrophobe.
