What is Contact Angle?

The contact angle is the angle, conventionally measured through the liquid, where a liquid-vapor interface meets a solid surface. It quantifies the wettability of a solid surface by a liquid via the Young equation. A given system of solid, liquid, and vapor at a given temperature and pressure has a unique equilibrium contact angle. However, in practice a dynamic phenomenon of contact angle hysteresis is often observed, ranging from the advancing (maximal) contact angle to the receding (minimal) contact angle.

How to Calculate Contact Angle Hysteresis?

Contact Angle Hysteresis calculator uses Contact Angle Hysteresis = Advancing Contact Angle-Receding Contact Angle to calculate the Contact Angle Hysteresis, The Contact Angle Hysteresis formula is defined as the difference between the advancing and receding contact angles. Contact Angle Hysteresis is denoted by H symbol.
