Superhydrophobic surfaces exhibit excellent anti icing performance,and CuS is an important semiconductor material widely used in photothermal conversion materials.In this experiment,CuS nanowires were prepared on the surface of copper mesh.After modification with low surface energy substances,the copper mesh has superhydrophobic performance.Under outdoor sunlight exposure,due to the strong absorption of light by CuS nanowire films,water droplets and ice are not easily aggregated and condensed on its surface,delaying the condensation time of water droplets and effectively reducing their crystallization point,exhibiting good anti icing performance.
