Thermodynamic expressions for the free energy of contact angle hysteresis have been derived assuming that wetting can be modeled as an adsorption-desorption process. The cause of hysteresis is not specified; it could be due to surface imperfections or simply irreversible interaction of the contact l
Advancing and receding contact angles of four organic liquids and water were measured on a variety of polymer surfaces and silicon wafers using an inclinable plane. Contact angles varied widely from liquid to liquid and from surface to surface. Surface roughness was relatively unimportant. Instead,
