Corrosive inhibition behavior of well-dispersible aniline/p-phenylenediamine copolymers

► P(ANI-co-p-PDA)-F was synthesized in the presence of nonylphenol ethoxylate. ► P(ANI-co-p-PDA)-F had better dispersion than that of copolymer without surfactant. ► P(ANI-co-p-PDA)-F/epoxy coatings on carbon steel possessed good corrosion resistance.
