Abstract
An actual problem is searching of new pathways of increase of anticorrosion properties of an organic coating. In the field of practice and the theory of metal protection from corrosion recently there were novel trends. One of them – making and examination of the conducting polymers inhibiting corrosion of many metals. Influence of the amine hardener modified by polyaniline (PANi) on anticorrosion properties of epoxy coatings in various corrosion-active mediums was studied. The polarization studies have shown that the introduction of PANI in the epoxy polymer coating reduces the corrosion current density. Using electrochemical impedance spectroscopy has established that coatings containing of PANI, are less permeable due to its hydrophobic. It was showed, that PANi it can be used for increase of anticorrosion properties of manufacturing epoxy primer.
