New processing routes and materials for non-biocidal, antifouling (AF) coatings with an improved performance are currently much sought after for a range of marine applications. Here, the processing, physical properties and marine AF performance of a fluorinated coating based on a thermoplastic (non-crosslinked) fluorinated polymer are reported. It was found that the addition of lubricating oil and hydrodynamic drag reducing microstructures improved the AF properties substantially, i.e. the settlement of a marine biofilm, containing mixed microalgae including diatoms, was reduced to low levels. More importantly, the remaining fouling was removed from the coatings at low hydrodynamic shear rates and promising AF properties were obtained. Moreover, additional potential benefits were revealed originating from the thermoplastic nature of the coating material which might result in significant cost reductions.
目前，人们迫切需要开发新的处理路线和材料，以生产具有更好性能的非生物杀灭型、防污（AF）涂料，用于各种海洋应用。本文报道了一种基于热塑性（非交联）氟化聚合物的氟化涂料的加工、物理性能和海洋 AF 性能。研究发现，添加润滑油和流体动力减阻微结构可显著改善 AF 性能，即降低了含有混合微藻（包括硅藻）的海洋生物膜的沉降。更重要的是，在低流体动力剪切速率下，涂层上的剩余污垢被去除，获得了有前景的 AF 性能。此外，还揭示了源自涂层材料热塑性的额外潜在益处，这可能会带来显著的成本降低。
