Electric Paint Discourages Biofouling

Dec-09-12 Researchers have developed a paint that helps keep ship hulls clean using electrolysis, offering an alternative to the toxic paints currently in use.

The paint, which contains nanoscale electrically-conductive particles, is applied on top of a non-conductive primer. An electrical current, either from an onboard solar panel or land-based power, is sent through the paint, and that current is controlled by software in a way the causes the pH value of the paint’s outer surface to constantly change, deterring the growth of barnacles or other organisms.

Since most marine biofouling occurs while the ship is docked, the paint could help to significantly reduce organism growth without the need for harmful chemicals.
