Waterborne Antifouling Paints Containing Nanometric Copper and Silver against Marine Species.

Due to the concern to find an alternative to reduce the colonization (microfouling and macrofouling) or the biocorrosion of surfaces submerged for long periods in water, we evaluated the antifouling activity of a commercial paint added with silver nanoparticles (AgNP's) and copper nanoparticles (CuNP's), beside copper-soybean chelate, by electrolytic synthesis, using them in low concentrations (6.94 - 04 mg Ag g paint, 9.07 - 03 mg Cu g paint, and 1.
