An article with a liquid-impregnated surface (120), the surface (120) having a matrix of features (124) thereupon, spaced sufficiently close to stably contain a liquid (126) therebetween or therewithin, and preferable also a thin film thereupon. The surface (120) provides the article with advantageous non-wetting properties. Compared to previous non wetting surfaces (104), which include a gas (110) (e.g., air) entrained within surface textures (108), these liquid-impregnated surfaces (120) are resistant to impalement and frost formation, and are therefore more robust.
