摘要: Cassie and Wenzel formulas have been used extensively to model the apparent contact angles on rough surfaces. Theoreticians experimentalists, alike, noted that such are based homogenization theories, while useful, do not capture hysteresis which is determined by details of line motion. Thus, it immediate interest in context type formulas. To address this issue, we consider an ad-hoc generalization theory for Joanny de Gennes.(1) We establish its applicability reanalyzing angle data from literature drops states pillar-type roughness geometries. Using theoretical framework, possible focus advancing receding motions separately unlike analyses drop motion inclined planes quantify combined effects fronts. show how information about motion, during or...
