The Lotus Effect - Superhydrophobic Surfaces • The leaves of the lotus plant are superhydrophobic – water beads up on the surface of the plant and moves freely with almost no resistance making the leaves self-cleaning. Water Drops on a Lotus Leaf • The surface of the lotus leaf has 10mm sized bumps which are coated by nanometer sized waxy crystals – extremely hydrophobic • Superhydrophobic in fact! • The water does not wet the entire surface of the leaf, but only the tops of the roughness. • Contact angle approaches q = 180o (the contact angle with air)
Hydrophobic vs. Superhydrophobic Hydrophobic Superhydrophobic • Droplets don’t stick to superhydrophobic surfaces • Water-based stains don’t adsorb resulting in stain resistant textiles • Dirt is picked up by rolling drop as it moves resulting in a self cleaning surface • Droplets can be manipulated one at a time on these surfaces to synthesize or analyze nano or picoliters of material – nanofluidics • Snow and ice do not accumulate on these surfaces Dirt Superhydrophobic Surface
Make Your Own Superhydrophobic Surfaces – Part I • Need: two identical pieces of Teflon, sandpaper (240 grit) and a pipette full of water. • Keep one piece of Teflon smooth. • Lightly sand the second piece of Teflon with a random motion of the sandpaper to impart micron and nanometer size surface roughness. • Experiment: • Place a small drop of water on the smooth Teflon surface. • Tilt the surface through vertical. • Does the drop stick or slide? • Now place a small drop on the sanded Teflon surface • Tilt the surface through vertical. • Can you get the drop to stick? • Adding micron and nanometer surface roughness can have a big impact on how drops adhere to and wet a surface Smooth Teflon Sanded Teflon
Make Your Own Superhydrophobic Surfaces – Part II • In the first experiment we changed surface roughness to make a hydrophobic surface superhydrophobic here we will change the hydrophobicity of an already rough surface • Need: Regular sand and “Magic Sand” (sand treated to make it hydrophobic) • Need: Two shallow pans/plates, two cups, two spoons and water • Experiment 1: • Cover the bottom of one pan with regular sand and the other with magic sand. • Place a small drop of water on each. • What do you observe? • Agitate/shake the pan. • Does the drop stick or slide? • Experiment 2: • Fill two cups with water. • Pour regular sand into one cup and magic sand into the other. • What do you observe? • Does the magic sand get wet? • Use a spoon to move sand around. Bring it to the surface and see what happens! Magic Sand
d w Using Superhydrophobic Surfaces to Reduce Drag • We are currently using superhydrophobic surfaces to develop a passive, inexpensive technique that can generate drag reduction in both laminar and turbulent flows. • This technology could have a significant impact on applications from microfluidics and nanofluidics to submarines and surface ships. • How does it work? The water touches only the tops of the post and a shear-free air-water interfaces is supported – effectively reducing the surface area. • Currently capable of reducing drag by over 70% in both laminar and turbulent flows!

The GENMAR GEORGE T (Japan Universal Shipbuilding, Tsu shipyard) Can These Surfaces Have a Real Impact? • Current Energy Resources – Fossil Fuels • Increasing scarcity • Increasing cost • Dangerous to maintain security • Ocean-going vessels accounted for 72% of all U.S. imports in 2006 • Technology could be employed to make ships more efficient or faster • Friction drag accounts for 90% of total drag experienced by a slow moving vessel • A 25% reduction in friction drag on a typical Suezmax Crude Carrier could… • Save $5,500 USD / day in #6 fuel oil • Prevent 43 metric tons of CO2 from entering the atmosphere each day 60μm
Why Size Matters • To support larger and larger pressures and pressure drops, the spacing of the roughness on the ultrahydrophobic surfaces must be reduced into the nanoscale. • Currently developing processing techniques for large area nanofabrication of superhydrophobic surfaces with precise patterns of surface roughness. • Roll-to-roll nano-imprint lithography – a cutting edge tool.

Why Roll-to-Roll Nanoimprint Lithography • Roll-to-roll technology will enable fabrication of nanostructured materials and devices by a simple, rapid, high volume, cost-effective platform. • Current cost of nanofabrication is $25,000/m2 • This technology capable of pushing it to $25/m2 • Will help address many of the challenges facing society.

Nanomanufacturing - the essential link between laboratory innovations and nanotechnology products.
Nanomanufacturing • Processes must work at a commercially relevant scale • Cost is a key factor • Must be reproducible and reliable • Environmental Health and Safety must be under control • Nanomanufacturing includes top-down and bottom-up techniques, and integration of both • Must form part of a value chain
