为了解决积冰引起的问题，研究人员进行了各种尝试，以获得防冰表面，其中超疏水表面已被批准为防冰应用的理想候选者。尽管人们对超疏水表面的防冰性能进行了广泛的研究，但超疏水表面的防冰性能与防结露性能之间的关系还有待研究。本研究制备了具有不同表面微结构的超疏水涂层。通过控制SiO2纳米粒子与聚酯粉末的摩尔比来调节表面形貌。超疏水涂层具有均匀的表面微观结构，具有良好的抗结露性能。与其他涂层相比，具有空穴-孔隙复合表面结构的超疏水涂层具有上级防冰性能。研究了防冰与防凝露性能之间的关系。结果表明，超疏水表面的防凝露性能与防冰性能之间并不存在简单的相关性。此外，该涂层还具有拒油性、持久的超疏水性和防污性。
To address the issues caused by ice accretion, researchers have made various attempts to obtain anti-icing surfaces, among which superhydrophobic surfaces have been approved to be an ideal candidate for anti-icing applications. Although extensive research has been conducted to date, the relationship between the anti-icing performance and the anti-condensation performance of superhydrophobic surfaces has yet to be investigated. In this study, superhydrophobic coatings with different surface microstructures were prepared. Tuning of surface morphology was conducted by controlling molar ratio of SiO2nanoparticles and polyester powders. The superhydrophobic coatings with uniform surface microstructures exhibit anti-condensation performance. Superhydrophobic coatings with cavities-pore combined surface structures demonstrated superior anti-icing performance to other coatings. The relationship between the anti-icing and anti-condensation performance was investigated. It is verified that the anti-condensation performance of the superhydrophobic surface do not have a simple correlation with the anti-icing performance. Furthermore, the coatings present oil repellency, durable superhydrophobicity and anti-fouling properties.
