An anti-biofouling material for use on marine equipment (e.g. cables) comprises a hydrophobically-modified base polymer, wherein the hydrophobically-modified base polymer comprises a base polymer with a backbone and a hydrophobically-derivatized chain extender coupled to the backbone. The hydrophobically-derivatized chain extender preferably comprises a fluorine- or silicon-containing moiety and the base polymer may be polyvinylchloride or polyethylene but is typically a polyurethane. The material may further comprise a biocide or a polymer filler. The anti-biofouling material may be produced by reacting a prepolymer with a hydrophobically-derivatized chain extender. Alternatively, the material may be formed by reacting a hydrophobically-modified prepolymer with a chain extender. Methods of applying the anti-biofouling material to the marine equipment are also disclosed, such as wrapping, dipping, or spraying the equipment with the material. In a broader aspect, a material for applying to marine equipment to prevent biofouling comprises a hydrophobically-modified base polymer. |
