Abstract

Corrosion is critical to a researcher since it has a substantial impact on both people's safety and the economy. A new approach based on a unique material has been employed to prevent rusting. Conducting polymer-composites are material types that show promise for anticorrosion by electrochemical synthesis of polyanethole(PA)/metals oxide nanocomposite (ZnO,TiO2) on Stainless Steel 304L (SS-304L) which plays as working electrode by using electropolymerization technique. The synthesized coating polymer was characterized by Fourier transform-infrared spectroscopy (FTIR) and atomic force microscopy (AFM) checkups. The findings demonstrated that when compared to the blank SS- 304L, PA/Nano composite and PA provide the strongest corrosion defenses for the metal. The results explained that the corrosion protection increased from 71% for PA film to 98% for PA/ZnO film and to 87% for PA/TiO2 at 298K .In addition, calculations were made for the kinetic and thermodynamic parameters (Ea, A, ∆H, ∆S and ∆G). Escherichia coli and Staphylococcus aureus, two gram-positive and gram-negative bacteria, were used to test the biological activity of polymeric film (E.Coli).

“…( 1) explains the synthesis of PACC polymer. In addition, to enhancing the efficiency of the polymeric coating PACC against corrosion, it was added 40 or 50 ppm of nano zirconium dioxide (ZrO 2 ) and nano magnesium oxide (MgO), respectively to the coating solution to produce PACC-ZrO 2 nanocomposite and PACC-MgO nanocomposite [24].…”
