Comparative impact of doping nano-conducting polymer with carbon and carbon oxide composites in alkyd binder as anti-corrosive coatings

Abstract

This study concentrated on producing anticorrosive coating depending on alkyd resin blended with polyaniline-carbon allotropes composites as filler. Polyaniline (PANI) and its composites were produced by doping of PANI with the carbon allotropes (graphene and multi-walled carbon nanotubes) and carbon-oxide allotropes (graphene oxide and multi-walled carbon nanotubes oxide) in different ratios through in situ chemical polymerization. The morphology of PANI and its composites were examined by transmission electron microscope (TEM), which proved that PANI composites appeared as a shell layer in core/shell structure with various overlay thickness depending on the adsorption type for polyaniline. The performance of the prepared coatings in cabinet salt agrees with electrical conductivity values where the best PANI/composite in conductivity value is the most efficient as an anti-corrosive coating.
