The influence of surface roughness on wettability -
Download our white paper to find out how it is measured
In this white paper we take an in-depth look at the principles underlying the 3D Topography Module method, resulting roughness parameters, and also the Wenzel theory used for roughness corrected contact angles. We also highlight applications and samples that are feasible for this method.
