Objective quantification of surface roughness parameters affecting superhydrophobicity
Yoonkyung Cho, Chung Hee Park
Abstract
or surface geometry, reducing the solid area fraction is a priority to ensure a stable Cassie-Baxter state. Horizontal-perspective roughness parameters had a great effect on dynamic wettability in the Cassie-Baxter state. The results confirmed that the proposed optical roughness parameters may be useful for quantitative analysis of the complex effects of roughness on superhydrophobic surfaces.
