Environmentally-friendly Anti-fouling Marine and Dairy Coatings

An Uncomplicated Strategy for a Complex Problem

There exists a critical environmental and economic need for non-toxic marine coatings which effectively control biofouling on vessels and other submerged structures. A feasible approach must be broadly effective but also must not be economically prohibitive or overly complex in its implementation. These coating technologies have also demonstrated efficacy in reducing dairy fouling during pasteurization.

What we are doing

The goal of our research is to develop coating technologies that synergistically combine anti-fouling and foul-release properties. Towards this goal, we have developed “PEG-silane amphiphiles” that can be readily formulated into coatings to boost resistance to marine biofoulers.
