Electro polymerization for (N-Terminal tetrahydrophthalamic acid) for Anti-corrosion and Biological Activity Applications


The present work reports the electrochemical synthesis of poly N Terminaltetrahydrophthalamic acid on stainless steel 316 (S.S), which acts as a workingelectrode, using an electrochemical polymerization technique. Fourier TransformInfrared Spectroscopy (FT-IR), Atomic Force Microscope (AFM) and ScanningElectron Microscope (SEM) characterized the formed polymer film. Corrosionprotection tests for coated and uncoated S.S with polymer film were studied in 0.2M hydrochloric acid (HCl) solution by using electrochemical polarization technique.Kinetic and thermodynamic activation parameters (Ea, A, ΔH*, ΔS* and ΔG*) werecalculated. The biological activity of the polymeric film was determined againstGram positive (Staphylococcus aureus; Staph.aure) and negative bacteria(Escherichia coli; E.coli).In addition, the polymer film was modified withnanomaterials(ZnOnnano and Graphene).
