MEAD Technologies, Inc. proposes to synthesize film forming biodegradable polymers, specifically a series of polyorganophosphazenes, to serve as primary vehicles for antifoul marine coatings. The coatings are non-metal-containing films which will controllably react with seawater at the desired rate to continuously provide a new surface for further erosion. The products of the degradation will provide a localized pHun favorable to barnacle and weed attachment, while not producing pollutants or biological toxins. Also, these thermally stable, elastomeric polymers should be less susceptible to impact damage. These will be secondary coatings applied over polyurethane coatings with additives, providing a smooth, hard finish for a glossy, good weathering film. In vitro and in vivo testing of coated panels in synthetic and natural seawater should clearly establish the commercial potential and provide the necessary data for optimization and scale-up of the polymer synthesis in a follow up Phase 2.Commercial Application:The potential commercial applications as described by the awardee:Based upon current consumption of antifoul coatings, approx. 1.5 x 108 pounds of copper and tin are introduced into the world's waterways annually, creating significant environmental problems manifested by polluted harbors and endangered marine life. Our proposed coatings will allow protection of ships hulls, but will not pollute the oceans. The potential market is worldwide.
