Imbibition by polygonal spreading on microdecorated surfaces
By Scott Tsai
Courbin et al use micropatterned surfaces to create different final shapes for spreading droplets. They show that they can control the final shape by changing the liquid. They describe a model for the velocity of the contact line, and they also show that the radii of the spreading drops scale with Washburn's scaling.
Wetting on patterened surfaces Most studies on the wetting of patterened surfaces is concerned with increasing the hydrophobicity of the surface via increased roughness.
