Patent ID: 7390560

Claim:
A coating system, said coating system comprising a coating array of 1 to 100 pairs of alternating antifouling and conductive layers, said coating array comprising: a) a conductive layer, said conductive layer: i. comprises one or more of the polymers polythiophene, polyfluorene, polyethylene, polyvinyl chloride, polyphenylene sulfide, polyaniline, polypyrole, polyacetylene, polythiophene, polyphenylenevinylene or their derivatives; ii. optionally comprises a conductive filler material, said filler material comprising one or more of conductive carbon, carbon fibers, carbon nanotubes, stainless steel, copper or aluminum; iii. has a thickness in the range of ¼ mil to 200 mils; and iv. has an electrical resistivity in the range of 10 8 ohm-cm to 1 ohm-cm; and b) an antifouling layer, said antifouling layer: i. comprises a low surface energy polymer, said polymer comprising one or more of polydimethylsiloxane, fluorinated polyurethane, fluorinated olefin, or their derivatives; and has a thickness in the range of ¼ mil to 300 mils; ii. whereby said conductive layer is bonded to said antifouling layer such that said bond is broken thus separating said conductive layer from said antifouling layer when said conductive layer is exposed to a pulse of energy of sufficient power and duration to heat said conductive layer without destroying said antifouling layer; and wherein said system comprises means for providing said pulse of energy to said conductive layer.
