How contact angle is influenced by roughness?
Download our white paper to find out
In this white paper, we take an in-depth look at the principles underlying the 3D Topography Module method. How roughness affects the contact angle and especially Wenzel theory used for roughness corrected contact angles is discussed. We also highlight applications and samples that are feasible for this method.
