摘要
Abstract Icing negatively impacts various industrial sectors and daily life, often leading to severe safety problems and substantial economic losses. In this work, a fluorinated resin coating with embedded graphene nanoflakes is prepared using a spin‐coating curing process. The results shows that the ice adhesion strength is reduced by ≈97.0% compared to the mirrored aluminum plate, and the icing time is delayed by a factor of 46.3 under simulated solar radiation power of 96 mW cm −2 (1 sun) at an ambient temperature of −15 °C. The superior anti/de‐icing properties of the coating are mainly attributed to the synergistic effect of the fluorinated resin with a low surface energy, the rough structure of the sandblasted aluminum plate, which reduces the contact area, and the embedded graphene nanoflakes with a superior photothermal effect. Furthermore, the hydrogen bonding competition effect between the exposed‐edge oxygen‐containing functional groups of the embedded graphene nanoflakes and water molecules further improves the anti‐icing properties. This work proposes a facile preparation method to prepare coatings with excellent anti/de‐icing properties, offering significant potential for large‐scale engineering applications.
