Abstract

In this paper, a facile, inexpensive, and environment-friendly method is developed to construct a superhydrophobic surface with hierarchical micro/nanostructures on the steel substrates. The superhydrophobic surface was fabricated by magnetic agitation of a mixture of micro and nanosized Zinc oxide (ZnO) suspensions on a substrate, after being modified with a low-surface energy monolayer of stearic acid, the as-prepared coating exhibits self-cleaning properties with a water contact angle of 162° and a sliding angle of 6°, and shows the good corrosion resistance. It is believed that the rapid and cheap technique have a promising future application for fabricating superhydrophobic surfaces on steel materials.
