“…Lan et al 7 reported that RTV coated insulators with different heights were sampled in areas heavily polluted by coal ash, and it was found that ultraviolet rays and rainwater were the main factors leading to their aging. At present, most researches on RTV are to mix nanoparticles into RVT to improve its electrical insulation and mechanical properties, but it is rare to improve the surface structure of RTV to prevent pollutants from accumulating on its surface for insulator anti‐pollution flashover 8–10 . Therefore, it is of great significance to develop and prepare self‐cleaning materials with excellent performance and simple preparation to solve the pollution flashover of transmission lines, which can reduce resource consumption and economic losses and provide convenience for people's production and life.…”

In order to investigate the effect of aluminum nitride (AlN) on the self‐cleaning and bouncing properties of room temperature vulcanized (RTV) silicone rubber, a superhydrophobic AlN/RTV composite with micro‐nano structure was prepared by powder scattering technology. The method combines the characteristics of RTV curing at room temperature, and has the advantages of simple operation, low cost and easy realization. Bouncing experiments, with different droplet sizes, different tilting angles and different temperatures, and self‐cleaning experiments were designed. The micro‐morphology of superhydrophobic surface was analyzed by Raman spectroscopy, scanning electron microscope, energy dispersive spectrometer, and interferometric 3D profilometer. The results show that the static contact angle and the rolling angle of AlN/RTV are 157.7 ± 0. 9° and 4.2 ± 0.7°, respectively. Many micro‐roughness structures were formed on the RTV surface by AlN, which reduced the contact area between droplets and the sample surface, so the samples had outstanding self‐cleaning and bouncing properties.
