Abstract Fabrication of surfaces with capability of repelling both water and oil is badly needed. Meanwhile, the widespread use of nanomaterials has also attracted great interest in this field. In this paper, we provided novel methods to synthesize nano amorphous tungsten oxide coatings on Al-Mg metals. After modification with FAS-17, the surface could obtain excellent superamphiphobic abilities with lower sliding angles and higher contact angles to water and oil. In addition, outstanding anti-oil pollutant and low adhesion were obtained. Furthermore, the as-prepared superamphiphobic surfaces could survive 200 cm abrasion distance under 19.6 kPa pressure on 1000 grid SiC sandpaper. It should be noted that this coatings could obtain different colors in different temperature. Meanwhile, we found that the droplets with lower surface energy and low viscosity are easier to bounce than the droplets with high surface energy and high viscosity. So the simple procedure and excellent superamphiphobicity about fabricating colorful tungsten oxide coatings have great potential in protecting Al-Mg metal and have potential applied in signals which need to prevent wetting or pollution by water and oils. On one level, this method about synthesizing nano amorphous tungsten oxide also has more promising using in other fields.

具有彩色超疏水表面研究的纳米功能化非晶氧化钨涂层的新型制备

摘要 迫切需要制造具有防水和防油能力的表面。同时，纳米材料的广泛应用也引起了该领域的极大兴趣。在本文中，我们提供了在 Al-Mg 金属上合成纳米非晶氧化钨涂层的新方法。用FAS-17改性后，表面可以获得优异的超疏水能力，具有较低的滑动角和较高的水油接触角。此外，还获得了优异的抗油污染物和低附着力。此外，所制备的超疏水表面可以在 1000 网格 SiC 砂纸上在 19.6 kPa 压力下承受 200 厘米的磨损距离。需要注意的是，这种涂层在不同的温度下可以得到不同的颜色。同时，我们发现具有较低表面能和低粘度的液滴比具有高表面能和高粘度的液滴更容易反弹。因此，制备彩色氧化钨涂层的简单程序和优异的超疏水性在保护铝镁金属方面具有巨大的潜力，在需要防止水和油的润湿或污染的信号中具有应用潜力。一方面，这种合成纳米非晶氧化钨的方法在其他领域也具有更大的应用前景。因此，制备彩色氧化钨涂层的简单程序和优异的超疏水性在保护铝镁金属方面具有巨大的潜力，在需要防止水和油的润湿或污染的信号中具有应用潜力。一方面，这种合成纳米非晶氧化钨的方法在其他领域也具有更大的应用前景。因此，制备彩色氧化钨涂层的简单程序和优异的超疏水性在保护铝镁金属方面具有巨大的潜力，在需要防止水和油的润湿或污染的信号中具有应用潜力。一方面，这种合成纳米非晶氧化钨的方法在其他领域也具有更大的应用前景。
