Abstract
The inhibition effect of 2-thiophene carbonitrile (2TCN) on the corrosion of mild steel in 0.5M H2SO4 has been predicted using quantitative structure activity relationship (QSAR) and evaluated with quantum chemical calculations, weight loss and electrochemical methods such as potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). QSAR model shows that the percentage inhibition efficiency %IE of this compound is 60%. Effect of concentration on the corrosion inhibition was investigated by using potentiodyanamic polarization and weight loss and the result has confirmed that the predicted compound has potential to inhibit corrosion on mild steel. Microstructure of the mild steel surface were observed using Nikon microscope which shows improvement of the surface in the presence of 2TCN.
