| 中文摘要: |
| 基于飞机快速、高效除冰的目的，设计与制备低冰粘附力的涂层，以期实现较低(甚至超低)的冰层粘附强度，减轻对现有高能耗主动防/除冰技术的依赖程度。总结了现有疏冰涂层的发展历程，基于不同涂层的防覆冰机理，以冰粘附性能或除冰外力作为主要技术指标来评估涂层的防/除冰性能，依次阐明了超疏水涂层、超润滑涂层和低界面韧性涂层的除冰机理，具体介绍了三者的疏水/冰效果，对比分析了各自的优劣性。其中重点阐述了低界面韧性涂层大面积除冰的优势，即在大面积结冰条件下，以冰层剪切粘附强度定义的(超)疏冰涂层材料，其除冰外力都受限于结冰面积，随着结冰面积的增加而成比例增加。但新型的低界面韧性涂层通过诱导材料表面萌生固-冰界面微裂纹，降低其界面断裂韧性，使得微裂纹在较低的除冰外力(甚至冰层自身重力)作用下快速扩展，从而实现冰层脱离。以此总结了设计、制备新型(超)疏冰涂层的方法，展望了低冰粘附力涂层在防/除冰领域的发展方向。 |

| Based on the purpose of rapidly and efficiently de-icing of aircrafts, it is necessary to design and prepare the coatings with low (or even ultra-low) ice adhesion, and reduce the dependence degree on the high energy consumption anti-icing/de-icing technology. The development history of existing icephobic coatings is summarized. Based on the anti-icing mechanism of different coatings, the ice adhesion performance is used as a main technical indicator to evaluate the anti-icing/de-icing ability of the coatings. The de-icing mechanism of hydrophobic coatings, super lubricating coatings and low-interfacial toughness coatings are successively clarified, the hydrophobic/icephobic effect of the three are specifically introduced, and their respective advantages and disadvantages are compared and analyzed. It focuses on the advantages of large-scale deicing of low-interfacial toughness coatings, that is, when facing large-scale icing conditions, the (super) icephobic coatings defined by the shear adhesion strength are limited by the icing area from the viewpoint of de-icing external force, which increases proportionally with the increase of the icing area. However, the low-interfacial toughness coatings can induce the formation of micro-cracks between the coatings and ice interface and reduce the interface fracture toughness. This allows the micro-cracks to rapidly expand under the action of low de-icing force (even the ice layer’s own gravity), thereby making the ice layer to be detached from the solid surface. In this way, the methods of designing and preparing a new type of (super) icephobic coating are summarized, and the development directions of low-ice adhesion coating in the field of anti-icing/de-icing are prospected. |
