Abstract
The present invention provides a composition for use as an antifouling agent and a method of decreasing fouling of a surface in a marine environment. The composition is a polymeric matrix, the polymeric matrix comprising subunits of at least one structural monomer and at least one ionic monomer. The ionic monomer comprising a salt, that is an anion that is a conjugate base of an acid having a pKa less than about 9 and at least one cation that is a cationic biocide. One embodiment includes guanidinium counterions that undergo ion exchange to slowly release a biocidal component.
