This study is focused on the development of tougher gels using combinations of acrylamide, fluoromethacrylate and a non-isocyanate urethane dimethacrylate (NIUDMA) crosslinker. The NIUDMA was tailored with 2, 3-epoxypropoxy propyl-polydimethylsiloxane segments E9 (MW = 0.36 kg mol-1), E11 (MW = 0.5-0.6 kg mol-1) and E12 (MW = 1-1.4 kg mol-1). A 3 level Taguchi design was used to evaluate the role of each component of the ternary copolymer gel on the elastic modulus and toughness. The toughness ranged from 2.5-7 MJ m-3 whereas the modulus ranged from 27-70 MPa. The formulations with the highest toughness and modulus were screened for their antifouling potential in biological assays against the microalga Navicula incerta and the bacterium Cellulophaga lytica. The E9 gels showed the best performance, achieving a 73% reduction in N. incerta cells and a 92% reduction in C. lytica biofilm remaining after water jetting treatments, when compared with the commercial Intersleek product IS700.

基于丙烯酰胺、氟甲基丙烯酸酯和非异氰酸酯氨基甲酸酯二甲基丙烯酸酯交联剂的坚韧两亲性防污涂料

这项研究的重点是使用丙烯酰胺、氟甲基丙烯酸酯和非异氰酸酯氨基甲酸酯二甲基丙烯酸酯 (NIUDMA) 交联剂的组合开发更坚韧的凝胶。NIUDMA 由 2, 3-环氧丙氧基丙基-聚二甲基硅氧烷链段 E9 (MW = 0.36 kg mol-1)、E11 (MW = 0.5-0.6 kg mol-1) 和 E12 (MW = 1-1.4 kg mol-1) 定制. 使用 3 级田口设计来评估三元共聚物凝胶的每个组分对弹性模量和韧性的作用。韧性范围为 2.5-7 MJ m-3 而模量范围为 27-70 MPa。在针对微藻 Navicula incerta 和 Cellulophaga lytica 的生物测定中，筛选具有最高韧性和模量的配方的防污潜力。E9 凝胶表现出最佳性能，N 减少了 73%。
