Low energy surfaces based on nanostructured films exhibit advancing and receding contact angles for liquids such that (1) the difference between the advancing and receding contact angles approaches zero and (2) the advancing and receding contact angles approach 180~. The low energy surface of the present invention comprises a nanostructured film coated with an organized molecular assembly (OMA). Advantageously, the chemical and wetting characteristics of the surface can be altered by changing the functionality of the OMA end groups exposed to the environment in contact with the surface of the nanostructured film.
L'invention porte sur des surfaces à basse énergie, à base de films nanostructurés présentant des angles de contact des liquides avançant et régressant tels que (1) la différence entre lesdits angles avoisine zéro et que (2) lesdits angles eux-mêmes avoisinent 180·. Lesdites surfaces à basse énergie comprennent un film nanostructuré revêtu d'un système moléculaire organisé (OMA). Les caractéristiques chimiques et de mouillage de la surface peuvent être modifiées par changement de la fonctionnalité des groupes d'extrémité exposés à un environnement en contact avec la surface du film nanostructuré.
