Pigments based on molybdates surface treated with conductive polymers and their properties in anticorrosive coatings

Popis výsledku v původním jazyce

This work describes the properties of molybdate-based pigments which were synthesized and subjected to surface treatment with 2 conductive polymers, viz. polyaniline phosphate (PANI) and polypyrrole phosphate (PPy), for use in protective coatings. Conductive polymers are currently attracting considerable interest in a number of sectors, among them the paint industry owing to their non-toxicity and high stability. Their oxidative and catalytic properties induce passivation processes on the surfaces of the metallic substrates, similar to those induced by compounds containing heavy metals. Owing to this, the new coating materials can be used to replace the toxic chromate-based corrosion inhibitors. Paints consisting of a solvent-based epoxy-ester resin asthe binder and the above-mentioned molybdate/PANI/PPY pigments were formulated and subjected to mechanical tests in order to assess the effect of the composite pigment particles on the paints' mechanical resistance. Anticorrosion efficie
