The main objective was to study the anticorrosion performance of poly(o-toluidine)/nano ZrO_2/epoxy composite coating.Poly(o-toluidine)/nano ZrO_2 composite was prepared by in situ polymerization of o-toluidine monomer in the presence of nano ZrO_2 particles.Fourier transformation infrared spectroscopy(FT-IR),UV-visible spectroscopy(UV-vis),X-ray diffraction(XRD),Scanning electron microscopy(SEM),and Thermogravimetric analysis(TGA) were used to characterize the composition and structure of the composite.Poly(o-toluidine)/nano ZrO_2 composite was mixed with epoxy resin through a solution blending method and the three components poly(o-toluidine)/nano ZrO_2/epoxy composite coating was coated onto the surface of steel sample by the brush coating method.The anticorrosion performance of poly(o-toluidine)/nano ZrO_2/epoxy composite coating on steel sample was studied by polarization curve and electrochemical impendence spectroscopy in 3.5% Na Cl solution as corrosion environment and also compared with that of poly(o-toluidine)/epoxy composite coating and pure epoxy coating.It was observed that the composite coating containing poly(otoluidine)/nano ZrO_2 composite has got higher corrosion protection ability than that of poly(o-toluidine).The electrochemical measurement results demonstrated that poly(o-toluidine) fillers improve the electrochemical anticorrosion performance of epoxy coating and the addition of nano ZrO_2 particles increases the tortuosity of the diffusion pathway of corrosive substances.
The main objective was to study the anticorrosion performance of poly (o-toluidine) / nano ZrO 2 / epoxy composite coating. Poly (o-toluidine) / nano ZrO 2 composite was prepared by in situ polymerization of o-toluidine monomer in the presence of nano Fluorier transformation infrared spectroscopy (FT-IR), UV-visible spectroscopy (UV-vis), X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Thermogravimetric analysis (TGA) were used to characterize the composition and structure of the composite. Poly (o-toluidine) / nano ZrO 2 composite was mixed with epoxy resin through a solution blending method and the three components poly (o-toluidine) / nano ZrO 2 / epoxy composite coating was coated onto the surface of steel sample by the brush coating method. anticorrosion performance of poly (o-toluidine) / nano ZrO 2 / epoxy composite coating on steel sample was studied by polarization curve and electrochemical impendence spectroscopy in 3.5% NaCl solution as corrosion environment and also com I was observed that the composite coating containing poly (otoluidine) / nano ZrO 2 composite has got higher corrosion protection ability than that of poly (o-toluidine) . The electrochemical measurement results of that poly (o-toluidine) fillers improve the electrochemical anticorrosion performance of epoxy coating and the addition of nano ZrO 2 particles increases the tortuosity of the diffusion pathway of corrosive substances.
