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° and < 5°, 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.
