LaitonLes laitons sont des alliages jaunes, très ductiles et malléables, composés essentiellement de cuivre et de zinc, aux proportions variables, dont la fabrication directe à partir de minerais appropriés était déjà maîtrisée par les métallurgistes avant l'Antiquité. Selon les propriétés visées, ils peuvent aujourd'hui contenir d'autres éléments d'addition comme le plomb, l'étain, le nickel, le chrome et le magnésium, dans des proportions très modérées.

| Résumé : |
In this work, a superhydrophobic and superoleophilic brass mesh had been prepared. The prepared sample displayed a water contact angle (WCA) of 160o and was characterized by field emission scanning electron microscope (FE-SEM), white light interferometer (WLI), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) techniques. Besides, a high-speed camera was used to study the impact process of a droplet on the surface of the prepared sample. The superhydrophobic brass mesh exhibited excellent self-cleaning ability, environmental adaptability, corrosion resistance (η = 98.9%), and delayed icing ability (~ 45 min). Furthermore, the superhydrophobic mesh could be used as a filter to fast and efficiently separate various kinds of oils (light and heavy oils) and oil pollutants in daily life and industry. The superhydrophobic filter could be reused 50 times for oil-water separation without any apparent decrease in its separation capability. Thus, the superhydrophobic brass mesh prepared by a simple method holds promise for various applications in the industrial field of oil-water separation. |
