Abstract

Interpolymer complexes of polyaniline were synthesized by using a template-guided synthetic method. A water-borne double-strand polyaniline was used as additive to commercial water-borne epoxy primers. The electroactive, water-borne primer was coated on aluminum alloys by electrophoretic coating process. Uniform coatings on AA7075, AA2024 and AA6061 alloys were obtained and were used for salt-spray, sea water immersion and filiform corrosion tests. Corrosion test results show that the conducting polymers are effective in inhibiting corrosion with small amount of conducting polymer as additive to the epoxy primers.
