Abstract

Slippery Liquid Infused Porous Surfaces (SLIPS) are a relatively new and promising development in the surface engineering world. Bio-inspired with superior omniphobicity and robustness, SLIPS have enjoyed success in several scientific applications, spanning multiple industries from the marine environment to the medical field. Inorganic fouling is one such challenge SLIPS have managed to overcome by disrupting both the deposition and adhesion mechanics of scale. To date, the primary focus has been on adapting stainless steels while more prevalent pipeline materials, such as carbon steel, have been overlooked. Here a unique and simple SLIPS system has been fabricated from X65 carbon steel, with the potential for creation of a SLIPS system in situ. Utilizing the topographical features of an FeCO₃ layer derived from CO₂ corrosion, two SLIPS, one with perfluorinated Krytox oil and another with 1-Butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide have been tested. The SLIPS have been validated with prevailing models in SLIPS design literature and shed further insight into how this is determined experimentally. This SLIPS combination spares the use of a functionalization layer between the substrate/lubricant interface and displays enhanced anti-fouling capabilities in a calcium carbonate (CaCO₃) scaling brine.

摘要

滑液注入多孔表面 (SLIPS) 是表面工程领域中相对较新且有前途的发展。SLIPS 受到生物启发，具有卓越的全能性和稳健性，在多个科学应用中取得了成功，涵盖从海洋环境到医疗领域的多个行业。无机污垢是 SLIPS 通过破坏水垢的沉积和粘附机制而成功克服的挑战之一。迄今为止，主要关注点一直是采用不锈钢，而忽略了更普遍的管道材料，例如碳钢。在这里，一个独特而简单的 SLIPS 系统由 X65 碳钢制成，具有在原位创建 SLIPS 系统的潜力。利用 FeCO _{3的地形特征}CO ₂腐蚀产生的层，已经测试了两种 SLIPS，一种使用全氟 Krytox 油，另一种使用 1-丁基-3-甲基咪唑鎓双(三氟甲基磺酰基)亚胺。SLIPS 已经通过 SLIPS 设计文献中的流行模型进行了验证，并进一步了解了如何通过实验确定这一点。这种 SLIPS 组合无需在基材/润滑剂界面之间使用功能化层，并在碳酸钙 (CaCO ₃ ) 结垢盐水中显示出增强的防污能力。
