Abstract

The wettability behavior of materials is the subject of numerous scientific investigations due to its significance and relevance to wide range of applications. Here we present comparative analysis of the wettability properties of glass coated by carbon-based nanostructures. Glass surfaces were coated with carbon nanotubes, nanodiamonds, fullerenes, and graphene by drop casting method. These coatings displayed a notable increase in the contact angle (CA) with water drop beads up to the superhydrophobic limit, except for the nanodiamonds coating, which depicted a significant decrease in the CA compared to the clean glass substrate. Moreover, carbon-based soot nanoparticles from candle flame deposited on the glass surface also imparted superhydrophobic characteristics to the glass with CA close to 152^°. Carbon nanoparticles were also deposited by femtosecond laser ablation, which is facile, efficient, and contamination-free technique to produce thin homogeneous film containing carbon nanoparticles, which improved the water repellent characteristic while maintaining its transparency in the longer-wavelength part of the visible spectrum. Our studies have shown that carbon nanotubes, fullerenes_, graphene and carbon soot depict superhydrophobic characteristics (CA > 150^°) and would introduce significant increase in the hydrophobic properties of the surface.

摘要

由于材料的重要性和与广泛应用的相关性，因此材料的润湿性成为众​​多科学研究的主题。在这里，我们对由碳基纳米结构涂层的玻璃的润湿性进行比较分析。通过滴铸法在玻璃表面涂覆了碳纳米管，纳米金刚石，富勒烯和石墨烯。这些涂层与水滴珠直至超疏水性极限的接触角（CA）显着增加，但纳米金刚石涂层除外，与清洁玻璃基板相比，CA显着降低。此外，来自烛光的碳基烟灰纳米颗粒沉积在玻璃表面上，也使CA接近152 ^°的玻璃具有超疏水特性。飞秒激光烧蚀还沉积了碳纳米颗粒，这是一种简便，高效且无污染的技术，可生产出包含碳纳米颗粒的均质薄膜，该薄膜改善了拒水特性，同时在可见光谱的较长波长部分保持了透明性。我们的研究表明，碳纳米管，富勒烯_，石墨烯和碳烟灰具有超疏水性（CA> 150 ^°），并会显着增加表面的疏水性。
