摘要： 以硅烷偶联剂 KH-570 改性纳米 TiO2 ，将其添加到丙烯酸树脂中，制得改性纳米 TiO2 复合丙烯酸树脂。 通过扫描电镜表征和接触角分析，发现 KH-570 改性纳米 TiO2 复合丙烯酸树脂成膜后具有明显的微米－纳米表面结构，成膜物的水接触角由 75°提高到 115°；海上挂板实验表明：KU-570 改性纳米 TiO2 复合丙烯酸防污涂料具有较强的防污性能，能够有效抑制海洋生物附着。

Abstract: TiO2 nano-particles were modified with silane coupling agent(KH-570),and then mixed with acrylic resin to form a nano-TiO2, composite acrylic resin. The scanning electron microscope (SEM)and contact angle analyzer indicated that the nano-TiO2 composite acrylic resin could form a film showing obviously micro-and/or nano-level surface structure and water contact angle increasing from 75° to 115°. The result derived from offshore field test indicated that the acrylic composite antifouling coatings based on nano-TiO2 modified with KH-570 exhibited high antifouling property and effectively inhibited the adhesion of marine organisms.
