Paper Abstract

We studied conductive polymers as an anti-corrosion coating on 7075-T6 aluminum alloys. A double strand polyaniline molecular complex was used as the coating material. The new double strand polyaniline complex is advantageous compared with the traditional polyaniline by improvements in processability and stability. Potentiodynamic tests show that the coating is effective for protection against corrosion. The results are consistent with a passive film formation protection mechanism. Further data shows the coating provides additional corrosion protection for the metal surface when a scratch is present on the surface, suggesting the coatings have damage resistant properties.
