Electrochemical Polymerization of Eugenol and Corrosion Protection Studies of Stainless Steel 304L Alloy

This research includes the preparation of a poly-eugenol layer on the surface of a stainless steel electrode by electropolymerization process, where the polymer was diagnosed using infrared spectroscopy and atomic force microscopy. The corrosion measurements of stainless steel 304L electrode were carried out before and after coating with polyeugenol in 3.5% of NaCl solution at four different temperatures in the range 298-328 K. Likewise, this study included the addition of nanomaterials such as ZnO and TiO2 to increase the efficiency of the polymeric layer formed against corrosion. The biological activity of the polymeric film was tested against bacterial Gram- positive Staphlococcus aureus (Staph.aure) and Gram-negative Escherichia coli (E.coli). Furthermore, the coating was treated with nanoparticles (ZnO and TiO2).
