- Abstract
In this paper, a facile approach is developed for preparing superamphiphobic surfaces with excellent anticorrosion properties on 304 stainless steel (SS) substrates. This proposed methodology involves fabrication of micro/nano-scale binary structures on SS substrates by a cycle-etching approach (cycles of hydrofluoric acid etching and ultrasonic cleaning), and final fluoroalkylsilane modification. Wettability measurements reveal that the fabricated SS surfaces become super-repellent toward water and peanut oil. By varying the times of cycle-etching, the authors compare the relationship between morphological change and wettability. The potentiodynamic polarization curves and electrochemical impedance spectroscopy suggest that the fabricated SS surfaces have superior corrosion resistance.
