Abstract An indole derivative containing a carbon-carbon double bond was purposefully synthesized by the Friedel-Crafts reaction based on 6-chlorine-1H-indole and characterized by IR, 1H NMR and 13C NMR. Antibacterial and inhibiting algae attachment experiments were carried out on the indole derivative. The indole derivative was indicated to have good antibacterial and algae inhibiting properties, then, was introduced into acrylic metal salt resin. Multifunctional acrylic metal salt resins were synthesized via free radical polymerization and polycondensation reactions using acrylic monomers, the indole derivative, metal salts and naphthenic acid. The synthesized resins were characterized by IR and 1H NMR, and the results showed that these target products were successfully synthesized. The self-polishing and antifouling properties of the multifunctional resins were investigated through inhibiting algae attachment experiment, dynamic simulation experiment, anti-protein adsorption experiment and antifouling test in marine environment. Acrylic metal salt resins containing the indole derivative were proven to have not only self-polishing properties but also better antifouling performance than pure acrylic metal salt resins.

含吲哚衍生物基团的新型环保型防污丙烯酸金属盐树脂的制备及性能研究

摘要 以6-氯-1H-吲哚为基础，通过Friedel-Crafts反应有目的地合成了含有碳-碳双键的吲哚衍生物，并对其进行了红外、1H核磁共振和13C核磁共振表征。对吲哚衍生物进行了抗菌和抑制藻类附着实验。吲哚衍生物被证明具有良好的抗菌和抑制藻类的性能，然后将其引入丙烯酸金属盐树脂中。使用丙烯酸单体、吲哚衍生物、金属盐和环烷酸，通过自由基聚合和缩聚反应合成了多功能丙烯酸金属盐树脂。合成的树脂经红外光谱和1H NMR表征，结果表明目标产物合成成功。通过抑制藻类附着实验、动态模拟实验、抗蛋白质吸附实验和海洋环境防污试验，研究了多功能树脂的自抛光和防污性能。含有吲哚衍生物的丙烯酸金属盐树脂被证明不仅具有自抛光性能，而且比纯丙烯酸金属盐树脂具有更好的防污性能。
