Abstract
In this study, copper oxide nanoribbons were fabricated on a Cu substrate by a simple liquid-solid reaction. The superhydrophobic copper oxide surface was formed by the immersion of the sample in an ethanol solution of stearic acid. The water contact angle on this surface was 153.6°. A slippery copper oxide surface was prepared by the immersion of superhydrophobic copper oxide in DuPont Krytox. Electrochemical measurement revealed that the corrosion resistance of the slippery surface was more stable than those of bare Cu and superhydrophobic surface. The inhibition efficiency reached up to 92.68%. This study provided a possible method for preventing copper corrosion.
