甲基丙烯酸酯和丙烯酸酯单体是防污（AF）和防污释放（FR）涂料的常用构件，以抵消海洋生物污损。它们以各种组合使用，并且经常组合成两亲材料。这项研究研究了两亲性乙二醇二环戊烯基醚丙烯酸酯（DCPEA）和相应的甲基丙烯酸酯（DCPEMA）与5 wt％的两性离子羧基甜菜碱丙烯酸酯（CBA）和相应的甲基丙烯酸酯（CBMA）的阻燃性能。合成了具有不同丙烯酸酯/甲基丙烯酸酯组成的一系列（共）聚合物，并针对硅藻Navicula perminuta的附着进行了测试以及短期动态场暴露实验。疏水性更高的甲基丙烯酸酯DCPEMA均聚物的性能优于其丙烯酸酯对应的DCPEA。CBMA和CBA的两性离子官能团的结合赋予两亲聚合物超低的结垢能力，使其易于附着在硅藻上，而在真实的海洋环境中，仅使用CBMA可以减少海洋生物结垢。而且，观察到与CBMA类似物相比，含CBA的涂层显示出不同的表面形态和粗糙度。特别地，当丙烯酸CBA与甲基丙烯酸DCPEMA混合时，发现高冲击。尽管涂层的润湿性相当，但与丙烯酸酯相比，研究的甲基丙烯酸酯通常显示出优异的耐污垢性。

Amphiphilic Zwitterionic Acrylate/Methacrylate Copolymers for Marine Fouling-Release Coatings

Methacrylate and acrylate monomers are popular building blocks for antifouling (AF) and fouling-release (FR) coatings to counteract marine biofouling. They are used in various combinations and often combined into amphiphilic materials. This study investigated the FR properties of amphiphilic ethylene glycol dicyclopentenyl ether acrylate (DCPEA) and the corresponding methacrylate (DCPEMA) blended with 5 wt % zwitterionic carboxybetaine acrylate (CBA) and the corresponding methacrylate (CBMA). A series of (co)polymers with different acrylate/methacrylate compositions were synthesized and tested against the attachment of the diatom Navicula perminuta and in short-term dynamic field exposure experiments. The more hydrophobic methacrylate DCPEMA homopolymer outperformed its acrylate counterpart DCPEA. Incorporated zwitterionic functionality of both CBMA and CBA imparted ultralow fouling capability in the amphiphilic polymers toward diatom attachment, whereas in the real ocean environment, only the employment of CBMA reduced marine biofouling. Moreover, it was observed that CBA-containing coatings showed different surface morphologies and roughnesses compared to the CBMA analogues. Particularly, a high impact was found when acrylic CBA was mixed with methacrylic DCPEMA. While the wettability of the coatings was comparable, investigated methacrylates in general exhibited superior fouling resistance compared to the acrylates.
