Introduction
Dynamic contact angles describe the processes on the interface liquid/solid during volume increase
(advancing angle) or volume decrease (receding angle) of a drop in horizontal position. As an
alternative to the static method (see ISO 19403-2), for the advancing angle always a surface area is
wetted, which was previously unwetted. For the receding angle, the contact angle during dewetting is
observed. The difference between advancing angle and receding angle is a sign of different chemical or
physical homogeneity (morphology, topology) or roughness. The receding angle is not suitable for the
determination of the surface energy.

dynamic contact angle
contact angle, which is measured during advancing or receding of the three-phase point
Note 1 to entry: For the definition of “contact angle”, see ISO 19403-1:2017, 3.1.9.
Note 2 to entry: The advancing or receding of the three-phase point can be achieved by changing the volume of
the liquid drop to be measured, by relative movement (immersing and pulling out) of a solid body to an interface,
or by moving the drop over the interface (e.g. rolling off).

Note 1 to entry: Generally, the advancing angle is used for the determination of the interface energy, in which
case, the measurement should be carried out close to the thermodynamic equilibrium. This is approximately
reached if there is no influence of, for example, the dosing speed on the contact angle.
