Abstract

     Poly [N-(1, 3-thiazo-2yl)]maleamic acid synthesized from corresponding monomer N-(1, 3-thiazo-2yl)maleamic acid (NTM) by using the process of electrochemical polymerization in aqueous solution at room temperature. The structure of the polymeric layer generated on the surface of (Low Carbon Steel (L.C.S)) (working electrode) was investigated by Fourier Transmission Infrared [FT-IR] and a scanning electron microscope [SEM]. The anticorrosion ability of a polymeric layer on low carbon steel (L.C.S) was investigated using a method of electrochemical polarization at temperatures ranging from (293 to 323) K, in a 3.50 percent NaCl solution. The activation parameters, both kinetic and thermodynamic for the L.C.S corrosion process were computed. The biological action of polymeric film had been tested against the gram positive, Staphylococcus aureus (S.aureus), and the gram negative, Escherichia coli (E.coli). The result shows that polymer and polymer nanocomposite provides the best performances for corrosion protection of the L.C.S by reducing its corrosion current density in comparison with the bare L.C.S. The effect of nanomaterials has been explored by adding them to solution of the monomer for improving the anticorrosion and anti-bacterial characteristics of polymeric films. The Oxide of Graphene was the nanomaterial used in this investigation (GO).
