Abstract: In this study, a zwitterionic-modified zinc acrylate copolymer was prepared via free-radical polymerization, and further mixed with cupric ion to form the zwitterion antifouling coatings. Infrared spectroscopy and contact angle measurements indicated that th zwttenon acrylate resin was prepared successfully and had low surface energy. The scanning e-lectron microscope was used to characterize the adhesive performance of algae on the surface of the prepared antifouling coating. Atom absorption spectroscopy measurement and biofouling as- says for the settlement of the algae in laboratory experiments and the ocean field showed that the prepared coating exhibited the improved antifouling property by a synergy of zwitterion polymer and cupric ion, in addition, had a relatively low leaching rate of cupric ion. The anti-fouling effect of the prepared coatings was similar with that of the overseas product of its kind as observed by the ocean field test for 6 months, indicating that the coating had a good resist-489 ance to adhesion of marine microorganism.
