Abstract
It has been shown that the introduction of a polyaniline dispersion into an alkyd-urethane emulsion leads to a decrease in the average particle size of the modified dispersion. The introduction of undoped polyaniline results in an increase in the stability of the modified dispersion over the entire studied range of contents. It was found that the introduction of doped (up to 2.6 wt %) and undoped polyaniline (up to 3.9 wt %) into coatings brings about an increase in both the initial curing rate and the content of the cross-linked polymer. Electrochemical impedance spectroscopy and polarization studies have shown that the introduction of polyaniline in both doped and undoped forms leads to a decrease in the corrosion current density of steel under the coatings and an increase in their impedance.
