Crosslinked polymeric materials based on a quaternary trimethylammonium compound were developed and evaluated as potential antifouling coatings. For this purpose, two water-soluble random copolymers, poly(4-vinylbenzyltrimethylammonium chloride-co-acrylic acid) P(VBCTMAM-co-AAx) and poly(N,N-dimethylacrylamide-co-glycidylmethacrylate) P(DMAm-co-GMAx), were synthesized via free radical polymerization. A water based approach for the synthesis of P(VBCTMAM-co-AAx) copolymer was used. Coatings of the complementary reactive copolymers in different compositions were obtained by curing at 120 °C for one day and were used to coat aquaculture nets. These nets were evaluated in respect to their release rate using Total Organic Carbon (TOC) and Total Nitrogen (TN) measurements. Finally, the antifouling efficacy of these newly-composed durable coatings was investigated for 14 days in accelerated conditions. The results showed that this novel polymeric material provides contact-killing antifouling activity for a short time period, whereas it functions efficiently in biofouling removal after high-pressure cleaning.

用于防污应用的基于水溶性三甲基铵共聚物的聚合物涂料

基于季三甲基铵化合物的交联聚合物材料被开发并评估为潜在的防污涂料。为此,两种水溶性无规共聚物,聚(4-乙烯基苄基三甲基氯化铵-共-丙烯酸)P(VBCTMAM-co-AAx)和聚(N,N-二甲基丙烯酰胺-共-甲基丙烯酸缩水甘油酯)P(DMAm-co- GMAx),通过自由基聚合合成。使用基于水的方法合成 P(VBCTMAM-co-AAx) 共聚物。通过在 120 °C 下固化一天获得不同组成的互补反应性共聚物的涂层,并用于涂覆水产养殖网。使用总有机碳 (TOC) 和总氮 (TN) 测量值评估这些网的释放速率。最后,在加速条件下对这些新组合的耐用涂层的防污功效进行了 14 天的研究。结果表明,这种新型聚合物材料可在短时间内提供接触杀灭防污活性,而在高压清洗后可有效去除生物污垢。
