Abstract: (307 Views)
Polyaniline metal organic framework (PAni-MOF) nanocomposite was synthesized via facile batch process in atmospheric pressure. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) were used to determine the morphology and chemical structure of the synthesized samples, respectively. Synthesized nanocomposite was added to a 0.5 M hydrochloric acid solution and corrosion of carbon steel immersed in the solution, was evaluated using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization corrosion testing. Results confirming the inhibition efficiency of PAni-MOF nanocomposite and its use reduce the rate of carbon steel corrosion in the environment of hydrochloric acid at a rate of 75 percent. Anodic protection mechanism of synthesize nanocomposite was confirmed via trend of open circuit potential changes and the analysis of electrochemical current noise data also showed a reduction in the probability of local corrosion in the presence of nanocomposite.
