Antifouling Surfaces

What is fouling

Fouling: When different kinds of materials stick to a surface in water

Crystals
Particles
Biomaterials Protein Bacteria Barnacle

Fouling is a Big Issue in Our World (transportation)

Barnacles on the bottom of a ship increases resistance during transportation

9% Energy Loss

Fouling is a Big Issue in Our World (membrane fouling)

Membrane replacement may constitute 25-30% of the operating cost of filtration

25-30%

Problems with classic methods to avoid fouling

If fouling material adheres strongly, washing is not effective

Cannot be eliminated easily

Chemical treatment is not environmentally friendly

Our Solution

Using surface "nano" patterns to generate designed flow, disturbing foulants before they can attach
