Basics of Superhydrophobicity Naturally Occurring Surfaces

• Advancing/receding contact angles, contact angle hysteresis, droplet collapse • Complex topography: dual length scales, curvature and re-entrant shapes • Defects and symmetric/random patterns 2. Materials Methods for Surface Fabrication • Fibers, textiles and fabrics • Lithography, aggregation/assembly of particles and templating • Phase separation, porous and etched • Crystal growth and diffusion limited growth 3. Beyond Simple Superhydrophobicit
