WebThe liquid film remains in the Wenzel or half-Wenzel state. The dewetting of the liquid film occurs after generating an initial dry spot on the substrate and forming a contact line between the liquid film, gases and the substrate. The dewetting is characterized by the continuous size growth of the contact line's radius. WebFor example, an ultrahigh CA can result from a Wenzel state as long as θ 0 > 90° and the surface roughness is sufficiently high. However, the liquid drops in a Wenzel state system …
