Preparation of poly (N-imidazolylmaleamic acid) /nanomaterial coating films on stainless steel by electrochemical polymerization to study the anticorrosion and antibacterial action (original) (raw)

Poly (N-Imidazolylmaleamic acid) PIM was synthesized from monomer (N-Imidazolylmaleamic acid) NIMin aqueous solution using electrochemical oxidation procedures. The polymer film was formed on Stainless steel electrodes (working electrode). Its structure has been examined by infrared, FTIR, scanning electron microscopy SEM and atomic force microscopy AFM studies indicate that the polymer was formed. Also, study the anticorrosion action of polymer film on stainless steel by electrochemical polarization method.Furthermore, enhanced the anticorrosion of polymerby nanomaterial such as (TiO 2 and ZnO (bulk-nano)) by adding to monomer solution. The results obtained showed that the corrosion rate of S-steel increased with temperature increase from 293K to 323K and the values of inhibition efficiency by coating polymer increase with nanomaterial addition. Kinetic and thermodynamic of activation parameters have been calculated for the corrosion process of S-steel in acidic medium before and after polymeric coating.Furthermore were studied the effect of the preparing polymer on some strain of bacteria.
