WebThe water contact angle (WCA) maximum of hydrophobic surfaces is circa 120 degree, for example of a bulk, flat Teflon surface. WCA is the angle formed tangential to the water droplet at the air–liquid–solid interface. A WCA less than 90 degree is an indication of a wettable surface; a WCA greater than 90 degree WebThe contact angle is the angle that is formed when a liquid comes into contact with a solid. The magnitude of the contact angle depends primarily on the ratio of the adhesive forces between liquid and solid and the cohesive forces of the liquid. When adhesive forces are large in relation to the cohesive forces, the contact angle is less than 90 ...
