Abstract:
Multi-layer anti-fouling coatings and methods of forming the same include a first biocidal layer formed on a surface. The first biocidal layer includes at least one biocidal biocide that kills a biofouling organism on contact with the first biocidal layer. A first biostatic layer is formed between the first biocidal layer and an external environment. The first biostatic layer includes at least one biostatic biocide that inhibits a biofouling organism from attaching to the first biostatic layer.

Claim (Index 22):
A method of protecting a surface from biofouling, comprising:\n applying a first biologically active inner polymer layer on a surface, the first biologically active inner polymer layer comprising at least one first biologically active agent that kills a juvenile stage of a biofouling animal organism on contact with the first biologically active polymer layer; applying a second biologically active outer polymer layer layer on the first biologically active inner polymer layer, the second biologically active outer polymer layer comprising at least one second biologically active agent, that inhibits and repels a larval stage of the biofouling animal organism, preventing the biofouling animal organism from attaching to the second biologically active outer polymer layer, and a mixture of nano-sized particles that include metal salts of pyrithione, impregnated as a suspension in the second biologically active polymer layer, that inhibit and repel the second larval stage of the biofouling animal organism and that inhibit biofilm buildup, wherein the second biologically active outer polymer layer limits exposure of a surrounding environment to the first biologically active agent; and a rigid sheet of fiberglass which provides structural support and stiffness to a polymer structure that includes the first biologically active polymer layer and which is covered by the second biologically active polymer layer.
