The Challenge

Excess build-up of biofouling on boat hulls leads to increased drag, greater fuel costs, and more frequent cleaning. Many existing coatings use biocides to kill the organisms that attach to the hull. The biocide can leach into the water and harm the surrounding ecosystem.

Innovation Details

The SLIPS® Foul Protect™ system creates an ultra-thin slippery surface repels almost all liquids and solids. The coating is made of a nanostructured porous material infused with a lubricating fluid to produce a smooth and highly slippery surface.

Biological Model

Pitcher plants trap insects and other small prey when they land on the rounded rim of the pitcher and fall in, ending up in a pool of digestive juices. The surface of the rounded rim is especially slippery, making it difficult for insects to grab hold and escape. The pitcher owes its slipperiness to a thin wet film on the surface, which drastically reduces friction between the plant and insect feet.
