用于铜网表面防覆冰的超疏水纳米线膜

Superhydrophobic Nanowire Film for Anti Icing on Copper Mesh Surface

超疏水表面表现出优异的防冰性能,而CuS是一种重要的半导体材料,被广泛应用于光热转换材料。在铜网表面制备出CuS纳米线,经低表面能物质修饰后,使得铜网具备了超疏水性能。在户外阳光的照射下,因为CuS纳米线薄膜对光的强吸收,使得水滴和冰不易在其表面聚集与凝结,延缓了水滴的凝结时间,有效降低了水滴的结晶点,表现出良好的防冰性能。

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 fi lms,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.
