Hydrophobic and icephobic surfaces Surface topography: spatially periodic • Stabilizes: air film on rough surfaces, hydrophobicity/icephobicity of textured concrete • Icephobicity of skunk cabbage Symplocarpusfoetidus
Vibro-levitation Vibration: temporally periodic • Stabilizes: non-adhesive interface, oil droplets, inverted pendulum • Change of phase: ‘freezing’ of droplets and cornstarch monsters, liquefaction of granular material, hardening of soft materials • ‘Indian-rope trick’: fibers with tunable stiffness Ideas from nature to design smart materials
