A simple and efficient strategy was developed to construct superamphiphobic surfaces on Cu substrates, showing repellency and low viscosity to water, ethylene glycol, and ethanol, as well as excellent self-cleaning properties and corrosion resistance. The method does not require complicated equipment and has advantages in cost and efficiency, making it suitable for industrial scalable production.
Nowadays, scalable manufacturing of superamphiphobic surfaces by a simple and efficient method remains challenging. Herein, we developed a facile and efficient strategy for constructing superamphiphobic surfaces on Cu substrates, including press molding, oxidation, and fluorination modification. The prepared superamphiphobic surface not only has repellency and low viscosity to water, ethylene glycol, and 30% ethanol (surface tension: 33.53 mN.m(-1)) but can also achieve excellent self-cleaning properties through these liquids. Scanning electron microscopy images revealed that this superamphiphobic surface had multiple hybrid structures, including microflowers, nanoneedles, and micropillar arrays. Owing to the high chemical stability of the C-F group, the obtained surface also exhibited excellent corrosion resistance. The preparation method of superamphiphobic surfaces with all these advantages does not require complicated equipment and has great advantages in terms of low cost and high efficiency, which not only endows this method with broad application prospects but is also makes it suitable for industrial scalable production.
