Electrothermal/Superhydrophobic\nAnti-Deicing Coating\nwith a Sandwich Structure Based on Micro-Nanomaterials

The freezing phenomenon poses significant challenges\nin many fields,\ncausing serious casualties and economic losses. Compared with traditional\nmeasures, active/passive coupled anti-deicing technology exhibits\ngreater adaptability and effectiveness in diverse scenarios. Herein,\nan electrothermal/superhydrophobic coating featuring a sandwich structure\nwas proposed for anti-deicing applications. Benefiting from the hydrophobic\nmodified micro-nanostructure, this superhydrophobic coating boasted\nremarkable abilities to delay icing and repel water adhesion, rendering\nit ideal for combating freezing rain. Under a certain electrothermal\npower density, the coating could be heated quickly and evenly. Furthermore,\nit has proven to be highly capable of enduring prolonged continuous\nheating and rigorous high–low-temperature cycling tests, delivering\nexceptional performance. To evaluate its dynamic anti-icing performance,\nicing wind tunnel tests were conducted, which demonstrated that the\ncoating can prevent freezing with the coupled electrothermal/superhydrophobic\nproperties, even under harsh icing environments. This work would inspire\nthe design of electrothermal/superhydrophobic anti-deicing coating\nwith a sandwich structure and promote the practical engineering applications.
