Edge effect of roughness in surface wetting

To analyze the relation between geometry surface and the wetting properties some models are compared. To know a comprehensive understanding about design of superhydrophobic surface, edge effect as an important parameter in geometry of roughness was studied. The various state of edge effect have been examined theoretically and confirmed by some experimental data. As the results, the balanced energy models are the best estimation approach to know edge effect
