Abstract Zinc acrylate self-polishing resin is an efficient marine antifouling material. Hower the influence mechanism of the hydrophilic-hydrophobic contents in the resin on its hydrolysis rate remains to be studied. In this paper, a series of zinc acrylate resins with different hydrophilic-hydrophobic contents were prepared by free radical polymerization. The copolymer structure, degradation mechanism and dynamic change of micro-nano structure were systematically investigated by combining infrared, contact angle, white light interferometer characterization and other tests. The results showed that with the increase of the hydrophilic component content in the zinc acrylate resin, its hydrophilicity was significantly enhanced, the wettability of the water film on the resin surface was improved, and the hydrolysis rate of the resin was greatly accelerated. In addition, the hydrolysis increased the surface roughness of the resin and the actual contact area between the water film and the resin, then accelerate the hydrolysis of the resin again. Therefore, in the zinc acrylate resin system, the precise control of its wettability and degradation rate could be achieved by adjusting the content of its hydrophilic-hydrophobic components, and the application and development of the zinc acrylate self-polishing resin in the marine antifouling field could be promoted.
