WebJul 16, 2013 · Hydrophilic and hydrophobic materials are defined by the geometry of water on a flat surface — specifically, the angle between a droplet’s edge and the surface underneath it. This is called the contact angle. If the droplet spreads, wetting a large area of the surface, then the contact angle is less than 90 degrees and that surface is ...
