Antifouling Paint

Caption

Commercially available antifouling paint (hard and soft formulation) with and without cerium dioxide nanoparticles was applied to stainless steel plates. Several control plates (stainless steel, native paint formulations and paint formulations with copper oxide) are displayed as well. The plates were attached statically to a boat bridge with direct exposure to fresh water. After 52 days, the control plates without cerium dioxide nanoparticles showed heavy fouling. In contrast, the plate with the cerium dioxide coating did not. Cu2O, the current gold standard, is added in commercially available coatings with a portion by weight of up to 50 percent.
