A bilayer coating superhydrophobic surface was developed by a simple one-step solvothermal method. This strategy can realize the introduction of low surface energy myristic acid/n-dodecyltrimethoxysilane and the fabrication of complex bionic micro/nano structure in one step, thereby further simplifying the manufacturing process. The as-obtained superhydrophobic surface has a CA of 157.6° and a SA of 2.0°. The bionic micro/nano structures are like the common herb sowthistle. The bilayer coating superhydrophobic surface has excellent self-cleaning properties, chemical stability and corrosion resistance. In addition, this strategy can effectively broaden the application of magnesium alloys and extend to other conductive metal materials.

A superhydrophobic bilayer surface was created with a contact angle (CA) of 157.3 ± 1° and sliding angle (SA) of 2° ± 0.5° using a simple one-step solvothermal process. The bionic micro/nano structures are similar to the flower of a carnation and common sowthistle, which plays an important role in resisting corrosion. In addition, potentiodynamic polarization shows that the superhydrophobic bilayer surface has excellent corrosion resistance. This preparation is beneficial as it is simple to fabricate, low cost, is easily prepared across large areas, and has excellent corrosion resistance, amongst other benefits. It can effectively broaden the application of magnesium alloys and extend to other conductive metal materials.
