我们在这里报告了一个非常快速和简单的过程，通过使用微波（MW）等离子体制造透明的超疏水表面。发现各种有机液体在MW氩等离子体中的反应在各种各样的表面上产生疏水性聚合物层，所述表面包括玻璃、聚合物表面、陶瓷、金属和甚至纸。在大多数情况下，这些聚合物沉积为由10-15 nm纳米颗粒（NP）组成的粗糙层。这种粗糙度与涂覆材料的化学疏水性质一起导致表面的超疏水性质。涂覆过程的典型反应时间为1-10秒。这些超疏水表面的稳定性在户外进行了检查，发现在直接暴露于环境下持续2-5天，当样品被石英盖保护时持续2个月。随后使用XPS、固态NMR和IR测量对层的化学组成进行详细表征研究。对产品进行了改进，大大提高了产品的户外稳定性。
We report herein on a very fast and simple process for the fabrication of transparent superhydrophobic surfaces by using microwave (MW) plasma. It was found that the reaction of various organic liquids in MW argon plasma yields hydrophobic polymeric layers on a large assortment of surfaces, including glass, polymeric surfaces, ceramics, metals, and even paper. In most cases, these polymers are deposited as a rough layer composed of 10-15 nm nanoparticles (NPs). This roughness, together with the chemical hydrophobic nature of the coated materials, is responsible for the superhydrophobic nature of the surface. The typical reaction time of the coating procedure was 1-10 s. The stability of these superhydrophobic surfaces was examined outdoors, and was found to last 2-5 days under direct exposure to the environment and to last 2 months when the sample was protected by a quartz cover. A detailed characterization study of the chemical composition of the layers followed using XPS, solid-state NMR, and IR measurements. Modifications were introduced in the products leading to a substantial improvement in the stability of the products outdoors.
