Abstract：
In this study, the de-icing performance is investigated between traditional carbon fibre-based coatings and novel MXene and poly(3,4-ethylenedioxythiophene)-coated single-walled carbon nanotube (PEDOT-CNT) nanocoatings, based on simple and scalable coating application. The thickness and morphology of the coatings are investigated using atomic force microscopy and scanning electron microscopy. Adhesion strength, as well as electrical properties, are evaluated on rough and glossy surfaces of the composite. The flexibility and electrical sensitivity of the coatings are studied under three-point bending. Additionally, the influence of ambient temperature on coating\'s electrical resistance is investigated. Finally, thermal imaging and Joule heating are analysed with high-accuracy infrared cameras. Under the same power density, the increase in average temperature is 84% higher for MXenes and 117% for PEDOT-CNT, when compared with fibre-based coatings. Furthermore, both nanocoatings result in up to three times faster de-icing. These easily processable nanocoatings offer fast and efficient de-icing for large composite structures such as wind turbine blades without adding any significant weight.
摘要：
在这项研究中,研究了传统碳纤维基涂层与新型MXene和聚（3,4-亚乙基二氧噻吩）涂层单壁碳纳米管（PEDOT-CNT）纳米涂层之间的除冰性能，基于简单和可扩展的涂料应用。使用原子力显微镜和扫描电子显微镜研究了涂层的厚度和形态。粘合强度,以及电性能，在复合材料的粗糙和有光泽的表面上进行评估。在三点弯曲下研究了涂层的柔韧性和电敏感性。此外,研究了环境温度对涂层电阻的影响。最后,用高精度红外摄像机分析热成像和焦耳加热。在相同的功率密度下，MXenes的平均温度升高84%，PEDOT-CNT的平均温度升高117%，与纤维基涂料相比。此外，两种纳米涂层的除冰速度可高达3倍。这些易于加工的纳米涂层为大型复合结构(例如风力涡轮机叶片)提供快速且有效的除冰,而不增加任何显著的重量。
