The self-polishing copolymers (SPCs) release biocides by the mechanism of a hydrolysis or ion exchange reaction of an acrylic polymer with seawater. So it has been variously applied to antifouling paints as the binder. The poly(ethylene glycol) (PEG) has been used as a drag-reduction(DR) additive in the pipeline. In this study we synthesized Zn-based SPCs resin and we selected 3 kinds of the monomer with poly(ethylene glycol) (PEG) for adding DR effect to SPCs resin. In each case, we used poly(ethylene glycol) methacrylate(PEGMA), poly(ethylene glycol) methyl ether methacrylate. The structures of the synthesized polymers were confirmed by using 1H-NMR and FT-IR. Then we checked drag-reduction rate by measuring PIV(particle image velocimetry). In addition, we examined the antifouling performance of the resins through the immersion test and abrasion test. |
