Nowadays, corrosion is a widely observed phenomenon in metal and one of the most important reasons of degradation in industrial parts. As a result, developing and applying the methods to reduce corrosion costs in industry is essential. In this research, emulsion polymerization route was used to prepare poly (3-aminobenzoic acid)@ multi- walled carbon nanotubes (P3ABA@ MWCNTs) hybrid conducting nanocomposite film. Different techniques like Fourier transform infrared spectroscopy (FTIR), X-ray diffraction
