我们证明了第一次制造的超疏水CuO涂层具有优异的自清洁能力，由定制的喷射雾化器喷雾热解技术。单斜晶系CuO微晶涂层在高速水射流冲击后仍保持稳定的Cassie-Baxter超疏水润湿状态（水接触角约为154°），实现了涂层的坚固性。雾化器的雾型气溶胶分布控制了CuO膜的最终形态，从而调节了超疏水特性。低成本（约1美元）的便携式袖珍雾化器提供可靠的氧化铜超疏水涂层在广泛的所需的主机表面。
We demonstrate for the first time the fabrication of a superhydrophobic CuO coating with excellent self-cleaning ability by a custom-made jet nebulizer spray pyrolysis technique. A stable Cassie–Baxter superhydrophobic wetting state (water contact angle, ~154°) was maintained even after high speed water jet impact on a monoclinic CuO crystallite coating, which realizes the robust feature of coating. The mist-type aerosol distribution from the nebulizer controls the resultant morphology of the CuO film, thereby tuning the superhydrophobic properties. The low-cost (~$1) portable pocket-sized nebulizer affords reliable CuO superhydrophobic coatings on a wide range of desired host surfaces.
