摘　　要：丙烯酸锌自抛光树脂是一种高效的海洋防污材料,树脂中亲/疏水组分含量对其水解速率的的影响机制有待研究。本研究通过自由基聚合制备了一系列亲/疏水单体含量不同的丙烯酸锌树脂,结合红外光谱、接触角测试和白光干涉等多种表征,对其共聚物结构、降解机制和微纳结构动态变化进行了系统性研究。结果表明:随着丙烯酸锌树脂中的亲水组分含量提高,亲水性显著增强,水膜在树脂表面的浸润性能提升,极大加快了树脂的水解速率。此外水解增大了树脂表面粗糙度,提高水膜与树脂的实际接触面积,从而进一步加快树脂水解速率。因此在丙烯酸锌树脂体系中,可通过调整亲/疏水组分含量,实现对浸润性和降解速率的精准调控,推动丙烯酸锌自抛光树脂在海洋防污领域的应用与发展。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.
