Abstract
The present invention is concerned with a superhydrophobic surface arrangement, an article having the same and a method of making same. The arrangement is configured for generating, upon contact by water droplets, pancaking bouncing and reducing liquid contact time. The arrangement has an array of posts residing on a surface and extending from the surface, said posts having an elongate configuration with a base portion at one end and an upper portion at an opposite end.
