Abstract

The first compound was prepared by dispersing polyaniline into polyamide-651via ball-milling. The second one was formed by removing bigger particles of the first compound by means of centrifugation. PANI and C-PANI coatings were prepared by mixing those two compounds with Epoxy resin E-51. The anti-corrosion performances and adhesion force of the coatings were characterized by immersing the samples in 12% NaCl solution at 95℃. The toughness of different coatings for different immersion time was also evaluated. The experimental results indicate that polyaniline can improve coating's toughness and anti-corrosion performance effectively. It was also found that C-2.0%PANI which could be effective in saline solution of high temperature for more than 70 days has the best combination property.
