Background: Today, corrosion has become a big challenge in various industries. The use of coating is a common method to reduce the corrosion rate and increase the corrosion resistance of metals in corrosive environments. But these methods have disadvantages such as need for advanced equipment and long reaction time [1]. Nowadays, the use of green and environment-friendly methods and materials has attracted the attention of researchers. Metal-organic frameworks are a class of porous materials that are formed by the interaction between metal ions and organic ligands. Electrochemical method has attracted attention due to shorter synthesis time, easy operation, lower cost and direct deposition of MOFs on different substrates [2]. Results: Morphological characterization showed Zn-MOF rod structures uniformly distributed on the surface. Polarization results show that the corrosion current density and corrosion potential changed to a lower current density and higher positive potential with the synthesis of Zn-MOF thin film on the substrate. Significance: In summary, we used a simple electrochemical deposition technique to manufacture Zn-based metal-organic framework thin films. The results obtained from XRD and SEM techniques proved the successful synthesis of Zn-MOF thin film on CS substrate. The results of electrochemical tests in 1M HCl solution showed that Zn-MOF thin films show good performance in corrosive environments and and effectively lower the rate of corrosion.
