This paper describes the results of a study of the anticorrosion efficiency of composite materials prepared by precipitating conductive polymer salts on the surface of synthesized pigment particles. Specifically, composite pigments with polyaniline phosphate and polypyrrole phosphate were prepared. The novelty consists in testing the anticorrosive properties of composite pigments based on tungsten and molybdate, which have been surface treated with salt conductive polymers. Strontium, zinc and ferric molybdates and tungstates were synthesized and described and then coated with the conductive polymer salts. Twelve composite material samples were prepared and described and paints containing them as pigments were formulated. A solvent-type epoxy-ester resin served as the binder. The volume concentrations of the composite materials in the paint were 1%, 5%, 10% and 15%. The paints were applied to steel panels and the anticorrosion efficiency of the composite pigments was measured in dependence on the conductive polymer salt type and pigment volume concentration. Paint samples containing a commercial zinc phosphate pigment were prepared as reference materials. The physico-mechanical properties of the paints were also measured: the paint films exhibited an outstanding mechanical resistance. The steel panels coated with the paints were subjected to accelerated cyclic corrosion tests, the results point to a very good anticorrosion efficiency of the organic coatings containing the composite particles examined.

W pracy omówiono wyniki badań skuteczności antykorozyjnej materiałów kompozytowych wytworzonych przez wytrącanie soli polimerów przewodzących na powierzchni zsyntetyzowanych cząstek pigmentu. Sporządzono pigmenty kompozytowe z fosforanem polianiliny i fosforanem polipirolu. Nowość polega na przebadaniu antykorozyjnych właściwości pigmentów kompozytowych na bazie wolframu i molibdenianu, które zostały poddane obróbce powierzchniowej solami polimerów przewodzących. Zsyntetyzowano molibdeniany i wolframiany strontu, cynku i żelaza, scharakteryzowano je, a następnie pokryto solami polimerów przewodzących. Sporządzono i scharakteryzowano dwanaście próbek materiałów kompozytowych i opracowano receptury farb zawierających je jako pigmenty. Jako spoiwo zastosowano rozpuszczalnikową żywicę epoksyestrową. Stężenia objętościowe materiałów kompozytowych w farbie wynosiły 1%, 5%, 10% i 15%. Farby nałożono na płytki stalowe i badano skuteczność antykorozyjną pigmentów kompozytowych w zależności od rodzaju soli polimeru przewodzącego i stężenia objętościowego pigmentu. Jako próbki odniesienia sporządzono farby zawierające handlowy fosforan cynku. Stalowe płytki pokryte farbami poddano przyspieszonym cyklicznym badaniom korozyjnym – wyniki wskazują na bardzo dobrą skuteczność antykorozyjną powłok organicznych zawierających badane pigmenty kompozytowe. Przebadano również właściwości fizyko-mechaniczne powłok i stwierdzono, że powłoki wykazywały wyjątkową odporność mechaniczną.
