Abstract
Methods of protecting a submerged surface from biofouling animal organisms include applying a first biologically active inner polymer layer on a surface, impregnated with at least one first biologically active agent that kills a juvenile stage of a biofouling animal organism. A second biologically active outer polymer layer is applied on the first biologically active inner polymer layer, impregnated with at least one second biologically active agent that inhibits a larval stage of the biofouling animal organism from attaching to the second biologically active outer polymer layer. The second biologically active outer polymer layer includes a friction-reducing additive selected from the group consisting of silicone powder, PTFE powder, molybdenum disulfide powder, graphene nano-platelets, graphene oxide, and fluorinated graphene powder.
