MANUFACTURED ARTICLE WITH A NANOSTRUCTURED SURFACE

摘要

The present invention concerns a manufactured article comprising at least one 1 nanostructured surface, wherein: - said nanostructured surface is made of a material having a surface energy of less than 25 m J/m², preferably less than 20 m J/m², and comprises an array of contiguous cells defining cavities, the cavities of the cells being separated from each other by intermediate solid 20 material walls, and - the cavities have an average height (H) and an average radius (R) which meet the conditions: R ≥ 5 nm, preferably R ≥ 10 nm; 2 R ≤ 250 nm, preferably R ≤ 200 nm, better R ≤ 150 nm and more preferably R ≤ 100 nm; and H ≤ 3R. The invention concerns also a method for designing a nanostructured surface comprising an array of juxtaposed cells defining cavities separated from each other by solid 30 intermediate walls.
