摘要：

In this work, inhibitory behaviour of the new azomethan compound (I-N-C8) was studied by electrochemical potentiodynamic polarization ( PDP), impedance spectroscopy (EIS), and electrochemical frequency modulation (EFM), mass loss measurement, and UV-Visible spectroscopy. The structure was determined by Fourier transform infrared spectroscopy FTIR and mass spectrometry. Also the thermotropic behaviour of the studied liquid-crystal was determined by differential scanning calorimetry (DSC). The results showed that, the prepared compound revealed liquid-crystalline properties and high inhibition efficiency of about 96 %. These results make it more preferred than other inhibitors, in addition to the low cost, more availability of raw material and reduction of pollution.
