title: Water droplet bouncing--a definition for superhydrophobic surfaces.
abstract: The ability of water to bounce on a surface provides an indication of many of the surface's properties. The technique described in this article uses water bouncing to determine the hydrophobicity of a surface, with a relationship established between water contact angle and number of bounces, which is dependent on the surfaces microstructure.
