Explicit Anticorrosion Properties of Superhydrophobic Zn–CaO Nanoparticle Derived from Oyster Composite Coating Functionalized with Ultra-Thin Films Silicone

Zn–CaO nanoparticles (CaOnp) functionalized silicone composite coating superhydrophobic was developed to reduced corrosion of steel used in structures and equipment in offshore mining explorations. Electrodepoistion and spraying method were used to produced the functionalized silicone superhydrophobic Zn–CaO nanoparticles (CaOnp) composite coating. The microstructure, electrochemical, Fourier-transform infrared (FT-IR), and X-ray diffraction (XRD) of the developed coating were determined. The findings demonstrated that the Zn–CaOnp deposits modified with silicone had water content angles that were significantly greater than those of the mild steel and Zn–CaOnp, exhibiting wettability behavior ranging from hydrophobic to superhydrophobic performance. It was also examined how the superhydrophobic surface prevented corrosion. The results showed that the Zn–CaOnp deposits' anticorrosion performance had been greatly enhanced by the superhydrophobic surface. The work have established that CaO-nanoparticles derived from oyster shell modified with silicone can be used in the production of superhydrophobic composites coating for good corrosion resistance.
