The icephobic surface is of great importance for many industries and has been gaining much attention worldwide. The present work investigated the three-line (i.e., before icing, icing, and after icing) synergistic icephobicity based on CNTs/PDMS nanocomposites with different surface categories. Meanwhile, the mechanisms underlying the observed phenomenon were also elucidated within the framework of classical nucleation theory, thermodynamic analysis, and Joule heating. That is, before ice: the rebounding behavior for successive water droplets was investigated to verify the dynamic icephobicity on the as-prepared nanocomposite surfaces; Icing: the thermodynamic (temperature-time) curves were plotted to analyze the icing phase transition process for static water droplets on the nanocomposite surface according to classical nucleation theory, and the wetting state transition during the icing process was also claimed. After icing: the electro-thermal function of the nanocomposite surface provided a final line for active deicing, which served as an alternative strategy if the first two passive defensive lines lose efficacy.

憎冰表面对许多行业都非常重要，并在全球范围内引起了广泛关注。目前的工作研究了基于具有不同表面类别的 CNTs/PDMS 纳米复合材料的三线（即，结冰前、结冰和结冰后）协同疏冰性。同时，在经典成核理论、热力学分析和焦耳热的框架内也阐明了所观察到的现象背后的机制。也就是说，在冰之前：研究了连续水滴的反弹行为，以验证所制备的纳米复合材料表面的动态疏冰性；刨冰：根据经典成核理论，绘制了热力学（温度-时间）曲线，分析了纳米复合材料表面静态水滴的结冰相变过程，并且还声称了结冰过程中的润湿状态转变。结冰后：纳米复合材料表面的电热功能为主动除冰提供了最后一道防线，如果前两条被动防线失效，这可作为替代策略。
