Abstract
The influences on the formation of contact angles using the inclined-plate and needle-in method have been studied on rough and homogeneous solid surface. It has been shown in part I that even on smooth silicon wafers a significant difference between the characteristic contact angles, which are dynamically measured with the inclined-plate and needle-in technique, is observable. This differences can be related to the different force balances influencing the motion of the triple line which are affected by the drop curvature and by different gravitational effects (differences in relative mass and position of the gravity center) during a dynamic contact angle measurement. In this study, we report about additional influences of a significant surface roughness on the force distribution at the triple line. The experimental investigations prove a significant difference between the characterisitic contact angles for both investigation techniques.
