Title (EN) DURABLE SUPERHYDROPHOBIC SURFACES
(FR) SURFACES SUPERHYDROPHOBES DURABLES
Abstract:
(EN) Durable superhydrophobic components have a superhydrophobic material disposed (e.g., disposed) thereon that exhibits an apparent advancing dynamic contact angle of ≥ about 150° and a roll-off angle of about ≤ 15° for water after at least 100 abrasion cycles. The superhydrophobic material may comprise a low surface energy material and a polymeric material. The superhydrophobic material may be self-healing and capable of recovering its wettability after damage. In yet other aspects, a component comprises a surface that is superhydrophobic and reduces drag in turbulent flow conditions. The surface has an apparent advancing dynamic contact angle of ≥ about 150° and a roll-off angle of ≤ about 15° for water, and a product of dimensionless roughness (k+) and a higher-pressure contact angle hysteresis of less than or equal to about 5.8. Methods of making such materials are also provided.
(FR) L'invention concerne des composants superhydrophobes durables comportant un matériau superhydrophobe disposé (par exemple, appliqué) sur ces derniers présentant un angle de contact dynamique d'avancée apparent ≥ environ 150° et un angle de glissement d'environ ≤ 15° de l'eau après au moins 100 cycles d'abrasion. Le matériau superhydrophobe peut comprendre un matériau à faible énergie de surface et un matériau polymère. Le matériau superhydrophobe peut être auto-cicatrisant et récupérer sa mouillabilité après un endommagement. Selon encore d'autres aspects, un composant comprend une surface superhydrophobe et réduisant la traînée dans des conditions d'écoulement turbulent. La surface a un angle de contact dynamique d'avancée apparent ≥ environ 150° et un angle de glissement ≤ environ 15° de l'eau, et un produit de rugosité sans dimension (k+) de même qu'une hystérésis d'angle de contact à pression plus élevée inférieure ou égale à environ 5,8. L'invention concerne également des procédés de fabrication de tels matériaux.
