ANTICORROSION PROPERTIES OF PEROVSKITES SURFACE-MODIFIED WITH CONDUCTING POLYMERS IN ALKYDE COATINGS

Abstract

The effect of pigment particle surface treatment with polyaniline and polypyrrole on the corrosion inhibiting properties of organic paints was investigated. Mixed oxides possessing the spinel and perovskite structures were synthesised for the study. Coatings based on an alkyde resin were prepared for the investigation of the corrosion protection properties of the pigments, the surfaces of which had been provided with a polyaniline and polypyrrole layers. Laboratory corrosion tests were applied to the paint films. Polyaniline phosphate was found preferable to polypyrrole as the modifying agent of the pigment surface regarding the pigment’s corrosion inhibiting efficiency.
