Abstract

This document specifies a method for the dynamic measurement of the roll-off angle of a liquid drop on a solid surface on a tilt stage. From the dynamic measurement, the advancing and receding contact angles of the drop rolling off can also be determined. The roll-off angle plays a role when evaluating, for example, easy-to-clean or anti-adherent surfaces.
