Synthesis and characterization of polyaniline-hydrotalcite-graphene oxide composite and application in polyurethane coating.

ABSTRACT: In this paper, a composite from polyaniline and graphene oxide-hydrotalcite hybrid (PAN-HG) was fabricated by direct polymerization of aniline using ammonium persulphate as an oxidant in the presence of a HG hybrid. The structure and morphological properties of synthesized PAN-HG composites were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), Raman spectra, and scanning electron microscopy (SEM) techniques. The electrochemical properties of the composite particles were also analyzed by potentiodynamic polarization curves to evaluate the corrosion inhabitation. The results were calculated by Tafel fitting and showed that the effective corrosion protection values were 73.11%, 88.46%, and 95.49%, corresponding to HG, 1PAN-HG, and 2PAN-HG. The influenc
