Corrosion Protection of Mild Steel by Polyaniline Modified with Kaolinite in 0.5M Sodium Chloride (NaCl) Solution.

Abstract

Among the conductive polymers used as an anti-corrosive coating, polyaniline (PANI) is the most studied conducting polymer. The addition of kaolinite into polyaniline-based coatings creates a protective barrier on the surface of mild steel, preventing moisture, oxygen, and other corrosive elements from permeating. This barrier inhibits the electrochemical processes that cause corrosion, extending the lifespan and durability of the coated mild steel substrate greatly.
