Anticorrosion efficiency of alkyd coatings containing polyaniline salts

Popis výsledku v původním jazyce

Polyaniline salts, which fall in the class of conductive polymers, find use in many branches of science and technology. Owing to their easy preparation, non-toxicity and high stability, they are also of interest in the formulation of organic coatings. The aim of this work was to assess the effect of polyaniline salts on the mechanical and corrosion properties of alkyd coatings. The polyaniline salts were prepared by oxidative polymerization of aniline using ammonium peroxodisulphate as the oxidative reagent. The polymerization process was conducted in an acid medium, using phosphoric acid, sulphuric acid or hydrochloric acid as the doping acid. The polyaniline salt density and oil number values were determined and the critical pigment volume concentration was calculated. Subsequently, the polyaniline salts were used in alkyd coatings at pigment volume concentrations 0, 1%, 5%, 10% and 15%. The organic coatings were subjected to an accelerated cyclic corrosion test in order to assess th
