The design of the icephobic surface represents an urgent challenge in the field of surface engineering with high application potential. In this work, we proposed the introduction of icephobic surface properties on the technically relevant material—polyetheretherketone/carbon fibers (PEEK/CF) composite. The developed method utilizes the simple and scalable electrochemical etching to induce a significant increase of surface roughness and subsequent chemical grafting for attachment of hydrophobic fluoro-containing chemical moieties. The surface morphology was characterized at different scales, using the profilometer, confocal microscopy, and atomic force microscopy (AFM) measurements. The success of chemical grafting was confirmed using the X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (IR) measurements. The surface properties were tuned to reach the superhydrophobic and Cassie–Baxter water drop states, minimizing the contact area between the drop and sample surface. The icephobic surface properties were tested through the measurements of the time delay of ice formation, precooled drop slipping, and estimation of ice removal force. It was convincingly demonstrated that optimal combination of physical and chemical treatment allows us reaching the icephobic properties on PEEK/CF composite. The main advantages of proposed procedure are its simplicity and scalability, which makes it highly attractive for the practical introduction of icephobic properties in the field of aircraft materials.

通过表面形态学和化学调节对空域复合材料进行多功能且可扩展的憎冰作用

疏水表面的设计是具有高应用潜力的表面工程领域中的紧迫挑战。在这项工作中，我们建议在技术上相关的材料-聚醚醚酮/碳纤维（PEEK / CF）复合材料上引入疏冰表面性能。所开发的方法利用简单且可扩展的电化学蚀刻来引起表面粗糙度的显着增加，并随后进行化学接枝以连接疏水性含氟化学部分。使用轮廓仪，共聚焦显微镜和原子力显微镜（AFM）测量，可以在不同尺度上表征表面形态。使用X射线光电子能谱（XPS）和红外能谱（IR）测量证实了化学接枝的成功。调整表面性能以达到超疏水和Cassie–Baxter水滴状态，从而最大程度地降低了水滴与样品表面之间的接触面积。通过测量结冰的时间延迟，预冷的液滴滑移和估计的除冰力来测试憎冰表面的性能。令人信服地证明，物理和化学处理的最佳组合使我们达到了PEEK / CF复合材料的憎冰性能。所提出的程序的主要优点是它的简单性和可扩展性，这使其在飞机材料领域中实际引入疏冰性具有很高的吸引力。通过测量结冰的时间延迟，预冷的液滴滑移和估计的除冰力来测试憎冰表面的性能。令人信服地证明，物理和化学处理的最佳组合使我们达到了PEEK / CF复合材料的憎冰性能。所提出的程序的主要优点是它的简单性和可扩展性，这使其在飞机材料领域中实际引入疏冰性具有很高的吸引力。通过测量结冰的时间延迟，预冷的液滴滑移和除冰力的估算，测试了憎冰表面的性能。令人信服地证明，物理和化学处理的最佳组合使我们达到了PEEK / CF复合材料的憎冰性能。所提出的程序的主要优点是它的简单性和可扩展性，这使其在飞机材料领域中实际引入疏冰性具有很高的吸引力。
