Polymer Coatings Containing Core-Shell Pigments with Polyaniline Shell

Аннотация

The effect exerted on rheological properties of polymer compounds by core-shell pigments with a shell of doped and undoped polyaniline was studied. In the presence of core-shell pigments with a doped polyaniline shell, the limiting content of the gel fraction increases, but the polymer network becomes less dense. Polarization studies show that the use of pigments with an undoped polyaniline shell leads to stronger inhibition of the corrosion process. As shown by electrochemical impedance spectroscopy, introduction of core—shell pigments enhances the protective properties of the coatings formed.
