liquid-impregnated surfaces, manufacturing methods and devices for their incorporation. the present invention is directed to an article with a surface impregnated with liquid, the surface having an array of protruding points on it, spaced close enough to stably contain a liquid between them or inside it, and a thin film on it is also preferable. the surface provides the article with advantageous non-wetting properties. compared to the previous non-wetting surfaces, which include a gas (e.g., air) entrained within the surface textures, these liquid-impregnated surfaces are resistant to impalement and ice formation, and are therefore more robust. |
