Claim Text:
1. An article comprising a non-wetting surface having a dynamic contact angle of at least about 90°, said surface comprising non-wetting features, said surface patterned with macro-scale features having a length scale L m that is larger than a length scale L n of the non-wetting features, the macro-scale features being configured to induce controlled asymmetry in a liquid film produced by impingement of a droplet onto the surface, thereby reducing contact time t c between the droplet and the surface to a value lower than where the droplet has a radius R, density ρ, surface tension γ, and the patterned surface having a pinning fraction φ of zero.
