Synthesis and Characterization of Polyaniline-Based Polymer Nanocomposites as Anti-Corrosion Coatings

Polymer nanocomposites of polyaniline (PANI)-based metal oxides (SiO2, CeO2, and TiO2A) were synthesized by in situ chemical oxidative polymerization rapid mixing a hydrochloric acid medium to evaluate compare their performance as anti-corrosion coatings on commercial 1018 steel 3.5% NaCl medium. The developed dispersing an alkydalic resin (AR) for subsequent electrochemical characterization. X-ray diffraction (XRD) analyses show that PANI has certain degree crystallinity its structure. incorporation oxide (MO) nanoparticles (NPs) into the polymer matrix was confirmed scanning electron microscopy energy-dispersive spectroscopy (SEM-EDS) analyses, while interaction with proven Fourier transform infrared (FT-IR) ultraviolet-visible (UV-vis). Thermogravimetric analysis (TGA) reveals infer greater resistance thermal decomposition PANI. Finally, use open circuit potential (OCP) study, Tafel curves, impedance (EIS) showed made TiO2A NPs exhibit best properties compared those SiO2 CeO2 NPs.
