Corrosion inhibition ,SAMs , Azepane-1-carbo dithioic acid ,

Self assembled monolayers is formed on copper using Azepane-1-carbo dithioic acid, under optimum conditions. Corrosion behaviour of copper is studied in neutral medium of 300 ppm using weight loss, electrochemical (impedance, potentiodynamic polarization)studies, FT-IR, SEM, EDX, XPS and AFM studies, of Azepane-1-carbo dithioic acid . An efficiency of 99% is observed. Potentiodynamic polarization studies have shown that SAMs formation controls both anodic and cathodic reactions. Scanning electron microsope studies have revealed the chemisorption of Nitrogen and Sulphur on the metal surface. CV studies have proved the stability of SAMs and through AFM studies the thickness of SAM formed have been proved. Thus SAMs formed using aminoacid offers a very good inhibition efficiency in protecting copper against corrosion.
