Abstract

Ice on the surface of wind turbine blades may result in power production losses and unsafe operations. An effective technological solution to the ice issue is coating de-icing. This study first constructed SiO₂ aerogel/CNTs (carbon nanotube) coating with photothermal de-icing by incorporating photothermal nanoparticles into the created nanoporous structure. The coating structure examined by SEM and EDS analysis demonstrates that CNT particles can be well captured by the three-dimensional nanostructure of SiO₂ aerogel and form a stable symbiotic skeleton. After that, we examined how the quantity of CNT doping affected the coating's surface morphology and photothermal properties. The findings demonstrated that the C-6 coating made from 0.6% CNTs performed best. Utilizing the photothermal effect of CNTs, it exhibited a steady rate of temperature increase and reached the target temperature of 153.4°C in 561 s upon near-infrared light (808 nm) irradiation. According to the results of experiments testing the photothermal performance, mechanical/chemical stability, and applicability of the coating, the coating has the advantages of being lightweight, provides quick de-icing, high stability, and simple production. This study not only increases the viability of using coating de-icing technology on wind turbine blades but also offers creative solutions to scientific investigation in the area of coating de-icing.

用于风力涡轮机叶片的二氧化硅气凝胶/碳纳米管光热除冰涂层研究

摘要风力涡轮机叶片表面结冰可能导致发电损失和不安全运行。涂层除冰是解决结冰问题的有效技术手段。本研究首先通过在纳米多孔结构中加入光热纳米粒子，构建了具有光热除冰功能的 SiO2 气凝胶/CNTs（碳纳米管）涂层。通过扫描电子显微镜（SEM）和电致发光分析（EDS）对涂层结构的研究表明，碳纳米管颗粒能很好地被二氧化硅气凝胶的三维纳米结构所捕获，并形成稳定的共生骨架。随后，我们研究了 CNT 掺杂量对涂层表面形貌和光热性能的影响。研究结果表明，由 0.6% 的 CNT 制成的 C-6 涂层性能最佳。利用碳纳米管的光热效应，它表现出稳定的升温速度，在近红外线（808 纳米）照射下，561 秒内就达到了 153.4°C 的目标温度。根据对涂层光热性能、机械/化学稳定性和适用性的实验结果，该涂层具有重量轻、除冰快、稳定性高和生产简单等优点。这项研究不仅提高了在风力涡轮机叶片上使用涂层除冰技术的可行性，还为涂层除冰领域的科学研究提供了创造性的解决方案。
