Abstract: Disclosed is a method of preparation of corrosion-resistant epoxy coatings. The coating composition contains two main corrosion resistant factors: The first one was Eemeraldine-Base polyaniline (EB-PANi), dissolved in the aminic hardener of epoxy. The other one was montmorrilonite clay, dispersed or exfoliated in the base component of epoxy resin. The hardener composition was prepared via dissolution of EB-PANi in functional amines like 3-(aminomethyl)-3,5,5-trimethylcyclohexan-1-amine adopting sonication and nanoscale filtering methods. The base component was prepared via gradual charging of MMT clay in epoxy resin via high-shear mixing plus sonication method. The morphology of the coatings during different stages of preparation was studied by optical microscopy and scanning electron microscopy and TEM. The corrosion-protective performance of the resultant coatings was evaluated by electrochemical impedance spectroscopy and salt spray tests.
