Problem
Biofouling:• Adds 330 lbs/meter2 in just 6
months• $70,000 – cost to clean a ship hull• 40 – 50% increased fuel cost• $2.1 billion – annual cost to US
Navy

Problem
Pipe Corrosion and Fouling:• $6 – 8 billion –
transmission pipelines• $276 billion – residential
plumbing costs
Bridge Corrosion:Annual cost of US Bridges: $7 billion

Problem
Aircraft Deicing:$5,000 per aircraft
Power Lines :One winter storm -$5 billion
6 Managed by UT-Battellefor the U.S. Department of Energy
Solution
Superhydrophobic – contact angle with a drop of water that exceeds 150 degrees
7 Managed by UT-Battellefor the U.S. Department of Energy
Roughening a hydrophobic surface increases the effective contact angle
Solution
Droplet on a normal hydrophobic surface Droplet on a superhydrophobic surface
