Liquid Drops on a Rough Surface
Liquid Drops on a Rough Surface
Abstract We consider a liquid drop sitting on a rough solid surface at equilibrium, a volumeāconstrained minimizer of the total interfacial energy. The largeāscale shape of such a drop strongly depends on the microstructure of the solid surface. Surface roughness enhances hydrophilicity and hydrophobicity properties of the surface, altering the ā¦
