Summary: We demonstrate a solution based hydrophobic coating on a hetero-nanostructured rough surface, which exhibits robust superhydrophobic properties. The surface is formed by growing ZnO nanorods on anodically etched Cu2O micro-needles, creating a micro-nano hierarchical rough surface. A thin layer of Teflon AF is applied as a low surface energy coating. The surface shows high static contact angle and low roll-off angle, as well as good durability and icephobic properties. This scalable solution-based fabrication method has potential applications in enhanced heat conduction and water-repellent coatings.

Summary: Superhydrophobicity is an important research topic for its ability to keep surfaces dry and self-clean. While low-surface-energy organic coatings are commonly used to create superhydrophobic surfaces, their defects can undermine the performance and lifespan of the coatings. Therefore, researchers have begun investigating the development of superhydrophobic surfaces without organic coatings.

Summary: Corrosion is a pervasive issue in various fields, leading to material degradation, environmental pollution, economic loss, and safety accidents. Superhydrophobic coatings have been considered a promising approach for corrosion inhibition due to their special surface functionalities, but their widespread application is hindered by mechanical and chemical weaknesses. A fluorine-free dual-layer microarc oxidation/superhydrophobic coating has been developed for corrosion protection, maintaining superhydrophobicity under various conditions and exhibiting significantly enhanced impedance modulus and corrosion inhibition efficiency. The synergistic effects of the microarc oxidation layer and superhydrophobic layer contribute to the enhancement of surface multifunctions, making the dual-layer coating a potential candidate for material protection applications.
