“…Chemically synthesized PANI by conventional route does not dissolve in common organic solvents and hence it has to be blended with other polymers for its applicability in coatings. Kalendová et al have reported the effect of addition of PANI together with other pigments, anticorrosive agents in paints [12][13][14]. They studied mainly the anticorrosive properties of these coatings in epoxy formulations by examining the physico-mechanical properties, extent of blistering etc.…”

“…The ZnFe 2 O 4 spinels are thermally stable [6], exhibit a high covering power, are insoluble [7,8], are resistant to aggressive media [9], and the cost of their preparation is reasonably low [2]. Spinel pigments enhance mechanical strength of the binder through a chemical reaction that produces cationic soaps, thereby reducing their solubility and tendency to saponify on exposure to a corrosive environment where hydroxy ions are created [10]. The objective of this work with zinc ferrite is to slow down or completely inhibit metal corrosion.…”

This work is focussed on the properties of organic coatings containing pigments whose surface was chemically coated with zinc ferrite (ZnFe 2 O 4 ) layer. Four silicate types with different particle shapes were selected as the cores: diatomite, talc, kaolin and wollastonite. The untreated particles exhibit a barrier effect. The aim of this project was to apply the surface treatment approach with a view to enhancing not only the model paint films' anticorrosion properties but also their resistance to physico-mechanical tests pursuant to ISO standards (cupping, bending, impact, adhesion). Other parameters examined included: particle size and morphology, density of the modified pigment, oil consumption, pH, conductivity, and electrochemical properties of the paint film. A solvent-based epoxy-ester resin was used as the binder and also served as the reference material. The pigment volume concentration (PVC) was 1% and 10%. During the last stage of the experiment, the paint films were exposed to a corrosive environment stimulating seaside conditions or conditions roads treated with rock salt. The accelerated cyclic corrosion test in a neutral salt mist atmosphere was conducted for 864 hours. The results served to ascertain a suitable environment for organic coatings.

“…Hence, the systems comprise pigment or filler particles, which are provided with a layer of an active compound; a conductive polymer and a suitable substance (pigment substrate) that provides an additional active effect [22][23][24]. The inner core should determine the paint's physical properties at the substrate metal/paint film interface, such as its adhesion to the substrate [25].…”

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.
