Adhesion of marine fouling organisms on the ship hulls causes many problems, including extra energy consumption, high maintenance costs and increased corrosion. One of the potential ways to solve these problems is to coat the immersed surface with the ammonium salt-based paints with the self-polishing property. These paints include tertiary amines as biocides which have effective biocidal and biodegradable properties without accumulation in the sea environment. However, ammonium salt-based coatings were too sensitive to seawater and became swollen before complete dissolution. In this study, poly(methacrylic acid)-b-polyurethane-b-poly(methacrylic acid) tri-block copolymers(TBCs) were synthesized by using hydrophobic polyurethane as macroinitiator in atom transfer radical polymerization(ATRP) of tert-butyl methacrylate. Poly(methacrylic acid) block length was controlled and the thickness of TBCs were measured by the laser scan micrometer to confirm the self-polishing property. |
