Marine biological fouling is defined as the undesired accumulation of microorganisms, plants, and animals on artificial surfaces immersed in seawater. This fouling can cause serious problems in the marine industry because it increases the surface roughness of ship hull and brings about additional costs by more fuel consumption, repainting, cleaning and plus loss of revenue. Fouling organisms, which attach on the surface of a paint film, are eliminated with the copolymer film which is decomposed by the hydrolysis of copolymers. In this study, we investigated polyurethane(PU) resins as a kind of new antifouling paint matrix by using polyethylene glycol(PEG), 4,4’-diphenylmethane diisocyanate(MDI), 2,2’-bis(hydroxyl methyl)-propionic acid(DMPA) and various quaternary ammonium salts(QAS). After synthesis, we tested physical self-polishing properties of the PU resins by the measurement of reduced film thickness in sea water. |
