Abstract

In the current study, the polyurethane acrylate (PUA) polymer was synthesized by the addition reaction between an isophorone diisocyanate (IPDI) and 2-hydroxyethyl acrylate and cured by polyol. Different properties of the synthesized PUA were determined through diverse analysis methods. The polyurethane acrylate (PUA)/natural filler-based composite (rhizome water extract of Costus speciosus) was prepared as an antifouling agent. The results revealed that the lowest weight loss percentages were detected at 2 wt% PUA/natural filler composite loadings with Escherichia coli (ATCC 23,282) and Pseudomonas aeruginosa (ATCC 10,145). The decreased weight loss percentage may be attributed to the well dispersed natural composite resulting in a slippery surface that can prevent fouling adhesion. It was concluded that the PUA/natural filler composite might be considered an eco-friendly and economical solution to the biofouling problem. KEY POINTS: • A novel strategy for anti-biofouling. • A new composite reduced Gram-negative bacteria.

摘要

在当前的研究中，通过异佛尔酮二异氰酸酯（IPDI）与 2-羟乙基丙烯酸酯的加成反应合成了聚氨酯丙烯酸酯（PUA）聚合物，并通过多元醇进行固化。通过多种分析方法确定了合成 PUA 的不同性质。将聚氨酯丙烯酸酯（PUA）/天然填充剂基复合材料（美丽贝母根茎水提取物）制备为防污剂。结果表明，在 2wt%PUA/天然填充剂复合材料负载下，大肠杆菌（ATCC 23,282）和铜绿假单胞菌（ATCC 10,145）的失重百分比最低。失重百分比的降低可能归因于天然复合材料的良好分散，形成了光滑的表面，可防止污垢附着。结论认为，PUA/天然填充剂复合材料可能被认为是解决生物污垢问题的一种环保且经济的解决方案。关键点：• 一种新的抗生物污垢策略。• 新型复合材料减少革兰氏阴性菌。
