Abstract : By Nahid Saeed Albeedh A thesis submitted for the requirements of the degree of Master of Science in chemistry [ Physical Chemistry] Supervised By Dr. Aisha A. Ganash Dr. Fowzia M. Al- Nowaiser Faculty of Science, Chemistry Department King Abdulaziz University Jeddah- Saudi Arabia Ramadan 1438 H – June 2017G Abstract In present work the corrosion resistance of 304 stainless steel (304 SS) coated with the homoplymer, copolymer and bilayer of polyaniline (PANI) with some of its derivatives as poly o-phenylenediamine (POPD) and poly o-methoxyaniline (POMA) has been investigated in 0.5 M HCl solution. The formed polymers were synthesis electrochemically from I M sulfuric acid solution containing the monomer by using cyclic voltammetry technique (CV). The formed polymers were characterized by cyclic voltammetry, UV–vis, Fourier transform infrared spectroscopy (FT-IR), Nuclear magnetic resonance spectroscopy (1HNMR), Thermogravimetric analysis (TGA) and Inductive coupled plasma (ICP) analysis. The surface morphology of polymer layers was studied by Scanning electronic microscope (SEM) image while the oxide film formed below these layers were analyzed by X-ray photoelectron spectroscopy (XPS). The Effect of monomer feed ratio through copolymer formation and change of synthesis number of cycles through bilayer formation for both of POPD and POMA on corrosion resistance was investigated in 0.5 M HCl at room temperature by using potential-time measurement, Tafel polarization, and EIS spectroscopy. The corrosion test showed that both copolymer formed from 0.05 M POPD and 0.01 M POMA and bilayers formed from 40POPD/10PANI and 20POMA/30PANI provide the best protection efficiency comparing with polyaniline as a homopolymer.
