摘要

【目的】降低传统防污涂料对毒性防污剂的依赖。【方法】以甲基丙烯酸异氰基乙酯与喜树碱反应得到喜树碱基甲基丙烯酸氨基甲酸乙酯单体（ CM）随后通过自由基共聚法将其与甲基丙烯酸甲酯、丙烯酸丁酯、甲基丙烯酸六氟丁酯、 2-丙烯酸 .2-甲氧基乙酯及，丙烯酰氧基三异丙基硅烷共聚，制备喜树碱基丙烯酸硅烷酯树脂（ CAUR）。【结果】 CAUR中 CM单体含量为 1%的树脂（ CAUR-1）涂层浸泡三角褐指藻藻液和小球藻藻液 24 h后抑制黏附率分别为 76. 5%和 79. 3%；空白组与 CAUR树脂涂层于小球藻藻液中浸泡 9d后的藻液浓度无显著差异。 CAUR树脂具有良好的抗藻性能，且对藻类无毒害作用。以 CAUR-1树脂为基料树脂制备防污涂料，在厦门海域浸泡 30 d防污性能良好。【结论】天然防污剂喜树碱接枝到甲基丙烯酸硅烷酯树脂侧链，可提高基料树脂的防污性能，降低毒性防污剂的添加量。

Abstract

［Objective］ To reduce the reliance of traditional antifouling coatings on toxic antifouling agents.［Methods］ Camptothecin-based methacryloyl carbamate monomer（CM） was synthesized by the reaction of isocyanatoethyl methacrylate with camptothecin，and it was subsequently copolymerized with methyl methacrylate，butyl acrylate，hexafluorobutyl methacrylate，2-methoxyethylacrylate and acryloyloxy triisopropylsilane by free radical copolymerization to prepare camptothecin-based acrylic silane ester resin（CAUR）.［Results］For coating based on the resin with 1% CM content（CAUR-1）， the inhibition adhesion rates against Phaeodactylum tricornutum and Chlorella vulgaris after 24-hour immersion in algal solutions were 76. 5% and 79. 3%，respectively. No significant algalconcentration difference was observed between the blank control group and CAUR coatings after 9-dayimmersion in Chlorella vulgaris solution，indicating that CAUR resin had excellent anti-algalperformance without toxic effects on algae. Antifouling coatings formulated with CAUR-1 demonstratedfavorable antifouling properties after 30-day immersion tests in Xiamen coastal waters.［Conclusion］ The graft of natural antifouling agent camptothecin onto the side chains of methacrylic silane ester resincould enhance the antifouling performance of the base resin and reduce the dosage of toxic antifoulingagents.
