Influence of polyaniline nanoparticles on the corrosion protection properties of epoxy nanocomposite coating abstract

In this study the anticorrosive properties of an epoxy coating loaded with polyaniline nanoparticles is investigated by means of Electrochemical Impedance Spectroscopy (EIS) and accelerated salt spray test. The blank epoxy coating was loaded with 0.1 wt % PAni nanoparticles. Through the monitoring of open circuit potential, an ennoblement effect was detected for the systems in the presence of a 3.5 wt.% NaCl solution. Also, an increase in the impedance at low frequency range was occurred by adding polyaniline nanoparticles. The OCP and EIS results indicate that possibly a passive layer formed on the substrate surface. In addition the coating with polyaniline nanoparticles had better performance to salt spray media.
