摘　　要：In this paper we report a multifunctional nanostructured surface on glass that, for the first time, combines a wide range of optical, wetting and durability properties, including low omnidirectional reflectivity, low haze, high transmission, superhydrophobicity, oleophobicity, and high mechanical resistance. Nanostructures have been fabricated on a glass surface by reactive ion etching through a nanomask, which is formed by dewetting ultrathin metal films （〈 10 nm thickness） subjected to rapid thermal annealing （RTA）. The nanostructures strongly reduce the initial surface reflectivity （-4%）, to less than 0.4% in the 390--800 nm wavelength range while keeping the haze at low values （〈 0.9%）. The corresponding water contact angle （0c） is -24.5~, while that on a flat surface is -43.5~. The hydrophilic wetting nanostructure can be changed into a superhydrophobic and oleophobic surface by applying a fluorosilane coating, which achieves contact angles for water and oil of -156.3~ and -116.2~, respectively. The multicomponent composition of the substrate （Coming~ glass） enables ion exchange through the surface, so that the nanopillars＇ mechanical robustness increases, as is demonstrated by the negligible changes in surface morphology and optical performance after 5,000-run wipe test. The geometry of the nanoparticles forming the nanomask depends on the metal material, initial metal thickness and RTA parameters. In particular we show that by simply changing the initial thickness of continuous Cu films we can tailor the metal nanoparticles＇ surface density and size. The developed surface nanostructuring does not require expensive lithography, thus it can be controlled and implemented on an industrial scale, which is crucial for applications.在这份报纸，我们在第一次，联合的玻璃上报导多功能的 nanostructured 表面大量光，弄湿并且耐久性性质，包括的低全向的反射率，低薄雾，高传播， superhydrophobicity， oleophobicity，和高度机械抵抗。Nanostructures 被反应离子通过 nanomask 蚀刻在玻璃表面上制作了，它被 dewetting ultrathin 金属电影形成(< 10 nm 厚度) 使遭到了到快速的热退火(RTA ) 。nanostructures 强烈减少起始的表面反射率(4%) ，当在低价值保留薄雾时，在 390800 nm 波长变化到不到 0.4%(<0.9%) 。相应的水接触角度(c ) 是 24.5 敶愠朠晩吗？？
