In this work, we proposed a facile approach to fabricate a superhydrophobic surface for anti-icing performance in terms of adhesive strength and freezing time. A hierarchical structure was generated on as-received Al plates using a wet etching method and followed with a low energy chemical compound coating. Surfaces after treatment exhibited the great water repellent properties with a high contact angle and extremely low sliding angle. An anti-icing investigation was carried out by using a custom-built apparatus and demonstrated the expected low adhesion and freezing time for icephobic applications. In addition, we proposed a model for calculating the freezing time. The experimented results were compared with theoretical calculation and demonstrated the good agreement, illustrating the importance of theoretical contribution in design icephobic surfaces. Therefore, this study provides a guideline for the understanding of icing phenomena and designing of icephobic surfaces.
在这项工作中，我们提出了一种简便的方法来制备具有抗冰性能的超疏水表面，该性能涉及粘附强度和冻结时间。使用湿蚀刻法在初始铝板上生成分级结构，随后进行低能化合物涂层处理。处理后的表面表现出优异的疏水性能，具有高接触角和极低的滑动角。通过使用定制设备进行了抗冰研究，结果表明该表面在防冰应用中具有预期的低附着力和冻结时间。此外，我们提出了一个计算冻结时间的模型。将实验结果与理论计算进行了比较，结果表明二者吻合良好，说明了理论贡献在设计疏冰表面中的重要性。因此，本研究为理解结冰现象和设计疏冰表面提供了指导。
