作为一种新型防冰技术，超疏水电热复合表面防冰具有良好的防冰效果和较低的能量消耗。基于超疏水表面润湿特性和电加热膜的加热特性，依据表面结冰机理，提出了超疏水-疏水表面分区与电热分区复合防冰方法。在结冰风洞中开展了翼型模型超疏水电热复合表面防冰试验研究，结果显示新型分区防冰方法防冰能耗最低，验证了该方法的可行性。试验结果与能耗分析表明：在过冷水滴的冲击下，前缘超疏水表面一旦结冰会造成结冰累积，需要更高的能耗，前缘疏水表面可以在较低能耗下保持湿态防冰效果；与常规超疏水电热防冰方法相比，超疏水-疏水表面分区与电热分区复合防冰能耗降低最大约64.2%的能耗；温度和风速对该方法的影响也相对较小。

As a new type of anti-icing technology， superhydrophobic electric thermal composite surface anti-icing has good anti-icing effect and low energy consumption. Based on the wetting characteristics of superhydrophobic surfaces and the heating characteristics of electric heating films， a composite anti-icing method of superhydrophobic-hydrophobic surface zoning and electric heating zoning is proposed according to the surface icing mechanism. Experimental research on the anti-icing of superhydrophobic electric thermal composite surfaces using an airfoil model was conducted in an icing wind tunnel. The results show that the new partitioned anti-icing method has the lowest anti-icing energy consumption， verifying its feasibility. The experimental results and energy consumption analysis indicate that freezing of the leading edge superhydrophobic surface will immediately cause ice accumulation and therefore require higher energy consumption under the impact of supercooled water droplets. The leading edge hydrophobic surface can maintain its wet anti-icing effect at lower energy consumption. Compared with conventional superhydrophobic electric heating anti-icing methods， the combination of superhydrophobic-hydrophobic surface zoning and electric heating zoning can reduce energy consumption by up to 64.2%， and the influence of temperature and wind speed on this method is relatively small.
