Efficient and Facile Method of Preparing Superamphiphobic Surfaces on Cu Substrates

Area of Science:

• Materials Science
• Surface Chemistry

Background:

• Scalable manufacturing of superamphiphobic surfaces using simple and efficient methods is a significant challenge.
• Superamphiphobic surfaces offer unique properties like liquid repellency and self-cleaning.

Purpose of the Study:

• To develop a facile and efficient strategy for constructing superamphiphobic surfaces on copper (Cu) substrates.
• To evaluate the liquid repellency, self-cleaning, and corrosion resistance of the fabricated surfaces.

Main Methods:

• The strategy involved a three-step process: press molding, oxidation, and fluorination modification of Cu substrates.
• Surface morphology was analyzed using scanning electron microscopy (SEM).

Main Results:

• The prepared superamphiphobic surface demonstrated repellency and low viscosity towards water, ethylene glycol, and 30% ethanol.
• Excellent self-cleaning properties were observed with these liquids.
• SEM revealed multiple hybrid structures, including microflowers, nanoneedles, and micropillar arrays, contributing to the surface properties.
• The superamphiphobic surface exhibited excellent corrosion resistance due to the chemical stability of the C-F group.

Conclusions:

• The developed method is cost-effective, efficient, and does not require complex equipment, making it suitable for industrial scalable production.
• The superamphiphobic surfaces possess desirable properties for various applications, including enhanced corrosion resistance and self-cleaning capabilities.
