【目的】本研究旨在制备具有高效海洋防污性能的新型树脂材料。【方法】创新性地将异噻唑啉酮类化合物 1，2-苯并异噻唑-3-酮（ BIT）与铜类化合物结合，成功制备新型含铜功能性单体（ BIT-乙酸铜）。随后通过自由基聚合反应，将不同含量的 BIT-乙酸铜接入丙烯酸树脂侧链，得到新型 BIT-乙酸铜树脂。采用核磁共振波谱仪和傅立叶变换红外光谱仪（ FT-IR）对合成的单体和树脂进行结构表征，并通过抑藻、抑菌测试和 60 d实海挂板测试评价其防污性能。【结果】 BIT-乙酸铜树脂对 3种藻类和 2种细菌均展现出优异抑制性，抑藻率最高达 80%，抑菌率接近 100%。60 d的实海挂板测试表明树脂具有良好的实海防污性能，且当 BIT-乙酸铜含量在 10%左右时，污损生物抑制效果最佳，同时涂层表面无开裂或脱落现象。【结论】制备的 BIT-乙酸铜树脂兼具高效海洋防污性能与稳定的力学性能。

［Objective］ This study aimed to develop a new resin material combining efficientmarine antifouling performance with stable mechanical properties.［Methods］ A novel copper-containing functional monomer（BIT-copper acetate）was prepared by innovatively combining 1，2-benzisothiazol-3-one（BIT）with a copper compound. Subsequently，through free radical polymerization， the monomer was then grafted at varying contents onto the side chain of acrylic resin to prepare the newBIT-copper acetate resin. The structures of the synthesized monomer and resin were characterizedusing 1H NMR and FT-IR spectroscopy. The antifouling performance was evaluated by algae andbacterial inhibition tests as well as a 60-day real-sea hanging plate test.［Results］The resin exhibited excellent inhibitory effects against three species of algae and two species of bacteria，with a maximum algae inhibition rate of 80% and a bacteriostasis rate close to 100%. The 60-day real-sea hanging plate test confirmed its good antifouling performance in a real marine environment. The optimal foulinginhibition was achieved when the BIT-copper acetate content was around 10%，and no cracking or peeling was observed on the coating surface.［Conclusion］The prepared BIT-copper acetate resindemonstrated both high antifouling efficiency and stable mechanical properties.
