摘要：The inhibition effect of 2-thiophene carbonitrile (2TCN) on the corrosion ofmild steel in 0.5M H2SO4 has been predicted using quantitative structureactivity relationship (QSAR) and evaluated with quantum chemicalcalculations, weight loss and electrochemical methods such aspotentiodynamic polarization and electrochemical impedance spectroscopy(EIS). QSAR model shows that the percentage inhibition efficiency %IE ofthis compound is 60%. Effect of concentration on the corrosion inhibition wasinvestigated by using potentiodyanamic polarization and weight loss and theresult has confirmed that the predicted compound has potential to inhibitcorrosion on mild steel. Microstructure of the mild steel surface were observedusing Nikon microscope which shows improvement of the surface in thepresence of 2TCN.
