【 摘 要 】

This paper presents a technological innovation that uses a subclass of glycerophospholipids as a booster biocide in antifouling paint. These glycerophospholipid PAF-analogs are economically and environmentally viable compounds because they are synthesized from a metal-free raw material source-soybean lecithin. The synthesis, which involves transesterification followed by an alkylation reaction, produced a mixture of glycerophospholipids that were characterized by mass spectrometry. Evaluation of the antifouling performance with field tests showed that the replacement of ordinary halogenated booster biocide with the synthesized product gave a better efficiency and an exceptional antifouling activity with a significant reduction in the coverage of the fouling macro-organisms.
