The Effect of Polypyrrole on Corrosive Properties of Organic Coatings Containing High Amounts of Zinc Metal Particles

Abstract:

The objective of this paper concerns reducing the zinc metal content in organic coatings while preserving their high mechanical efficiency. The two goals can be achieved by using conductive polymer as components of the protective coating. Polypyrrole (PPy) was investigated as the conductive polymer. PPy was specified using physico-chemical parameters. As a binder, the epoxy ester resin was used. Organic coatings were prepared by combining zinc metal with PPy. The anticorrosive efficiency of the prepared films was evaluated using the results of direct corrosion tests.
