Measurement technique and instrument for determining the lateral adhesion of drops


The new subproject C07 which has started with the second funding period is the result of findings from C03 during the first funding period. There, a method was developed with which the force required to move a drop over a surface can be measured directly. With this method inhomogeneities on surfaces can be characterized and the dynamic contact angles can be measured. In C07, the method is to be further developed and established as a multifunctional measuring device. In addition, scientific questions are to be clarified regarding the role of defects, impurities or an electric charge in contact angle hysteresis.

This project starts July 1, 2020.
