| Abstract | Polyaniline (PANI) and its composites with multiwalled carbon nanotubes (MWCNTs) were synthesized by chemical oxidative polymerization. High-resolution transmission electron microscopy (HR-TEM), thermogravimetric analysis (TGA), and Raman spectroscopy were used to characterize the investigated compounds. The synthesized composite is formulated as pigments in alkyd resin with different pigment-binder (P/B) ratios and investigated as anticorrosive coatings on carbon steel in 1 m HCl using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The protection mechanism of PANI occurred through the barrier and passivation effect on the carbon steel surface. The encapsulation and dispersion of MWCNTs into the PANI matrix promoted the anticorrosive efficiency of the alkyd coating. |
