We present a simple method for fabricating the superhydrophobic coatings on composite silicone rubber used for electrical outdoor applications. The coating is characterized by contact angles as high as 170° and is mechanically durable in contact with the aqueous phase. We discuss the impact of mechanical durability of the surface texture on the anti-icing performance of the coating on the basis of the experimental data on freezing delay of sessile aqueous droplets. A set of complementary data obtained in laboratory and outdoor experiments on freezing delay time, variation of wettability and practical work of adhesion for supercooled aqueous sessile droplets, impacting behavior of droplets at low negative temperatures, as well as the results of snow and ice accumulation in outdoor experiments indicate the very prospective icephobic properties of the developed coating.
我们提出了一种简单的方法来制备用于电气户外应用的复合硅橡胶的超疏水涂层。该涂层的特点是接触角高达 170°，并且在与水相接触时具有机械耐久性。我们根据关于静止水液滴冻结延迟的实验数据，讨论了表面纹理的机械耐久性对涂层抗结冰性能的影响。在实验室和户外实验中获得的一系列补充数据，包括过冷静止水液滴的冻结延迟时间、润湿性变化和实际附着力、低温下液滴的冲击行为以及户外实验中的积雪和积冰结果，表明所开发的涂层具有非常有前景的冰斥性。
