In this study, the authors investigated the anti-icing performance of a hierarchical slippery polymer thin film that is inspired by structures of the lotus leaf and Nepenthes pitcher plant. The polymer solution was mixed with the lubricant at the appropriate concentration to achieve slippery properties. The dry etching method followed by the spin-coating process was used to generate a uniform polymer microstructure on the thin film. The polymer nanostructure was then yielded by an additional plasma-etching method using carbon tetrafluoride (CF₄) gas. The anti-icing efficiency was then compared with that of the non-functional samples to demonstrate the advantages of combination in all criteria. Moreover, a theoretical prediction based on the free-energy approach was used to measure the nucleation time at the interface and illustrated good agreement with real-time measurement. The results propose a new and facile approach for outdoor anti-icing applications.

用于防冰应用的受自然启发的光滑聚合物薄膜

在这项研究中，作者研究了受荷叶和猪笼草猪笼草结构启发的分层光滑聚合物薄膜的防冰性能。聚合物溶液与润滑剂以适当的浓度混合以获得光滑的特性。干蚀刻法和旋涂工艺用于在薄膜上产生均匀的聚合物微结构。然后使用四氟化碳 (CF ₄） 气体。然后将防冰效率与非功能样品的防冰效率进行比较，以证明组合在所有标准中的优势。此外，基于自由能方法的理论预测用于测量界面处的成核时间，并与实时测量结果吻合良好。结果为户外防冰应用提出了一种新的、简便的方法。
