The objective of this paper concerns reducing the zinc metal content in organic coatings while preserving their high anticorrosive efficiency. The two goals can be achieved by using conductive polymers as components of the protective coating. Conductive polymers are attracting interest in many branches of science and technology, including the paint industry. Among important conductive polymers are polyaniline, polypyrrole and polyphenylenediamine. Major advantages of such conductive polymers include easy preparation, high stability and non-toxicity, owing to which such substances can be used as ingredients in organic coatings. Polyaniline phosphate, polypyrrole phosphate and polyphenylenediamine phosphate were investigated as the conductive polymer. These pigments were specified using physico-chemical parameters. Organic coatings were prepared by combining zinc metal with these pigments. The mechanical resistance of the prepared films was evaluated using the results of mechanical tests. The anticorrosive efficiency of the prepared films was evaluated using the results of direct corrosion tests.
