Calculate the critical contact angle for a pillar surface with a pillar diameter of 10 microns spacing (center to center) of 40 microns and height of 30 microns. Also, what is the expected apparent contact angle for water on the surface if its functionalized by a fluorosilane with a Young’s contact angle = 120º. The pillars are arranged in a square array.
