Superhydrophobic Myristic Acid/TiO2-Nickel Coating with Improved Corrosion Inhibition Property Created by Facile Electrodeposition and Modification Methods

In this article, nickel (Ni) coating was constructed on brass substrate by a simple electrodeposition technique, and myristic acid/TiO2 composite (MTC) modifier was used to modify Ni coating. The chemical composition and surface morphology of MTC confirm that myristic acid (MA) was successfully grafted on TiO2 nanoparticles. As a comparison, the structures of the Ni coatings were modified by MTC or MA. We found that both modified Ni coatings exhibit strong durability, self-cleaning and superhydrophobicity ability and have good prospect of decontamination. After Ni coating had been modified by MTC, the water contact angle and sliding angle of MTC-Ni were > 170 degrees and < 5 degrees, respectively. In addition, the MTC-Ni coating shows improved corrosion resistance, which can effectively retard the corrosion of brass. This novel and facile electrodeposition-modification route is believed to be widely applied to preparing superhydrophobic surfaces on metallic materials.

Automated summary

This article investigates the construction of nickel coating on brass substrate using electrodeposition technique and modification with MTC modifier. The modified Ni coatings show strong durability, self-cleaning, superhydrophobicity, and improved corrosion resistance. This electrodeposition-modification route holds potential for preparing superhydrophobic surfaces on metallic materials.
