pH-Responsive Nanostructured Polyaniline Capsules for Self-Healing Corrosion Protection: The Influence of Capsule Concentration

Abstract: Abstract. Nanostructured hollow polyaniline (PANI) capsules are good candidates for encapsulation of corrosion inhibitors and pH-responsive release when incorporated into organic coatings. In previous studies, the corrosion protection performance of PANI capsules, containing organic inhibitor 2-Mercaptobenzothiazole (MBT), was demonstrated. The present work studies the in uence of capsule concentrations (i.e., 0.3, 1, and 2 wt%) on the corrosion protection properties of the coating system. Anti-corrosion prope… Show more

“…The presence of PAN in the structure of the composite PAN-HG helps to enhance the protection on the CT3 steel surface due to the complicated protection mechanism of PAN. Those mechanisms are anodic protection, [45][46][47][48][49][50] cathodic protection, [50][51][52][53] controlled inhibitor release, [54][55][56] and barrier protection. 72 From the results of corrosion protection, both 1PAN-HG and 2PAN-HG have the same corrosion protection.…”

“…Then, the combination of the Fe cation and reduced PAN can give a passively complex layer to prevent the penetration of ions. Moreover, PAN was studied to fabricate a composite with either organic compounds, such as sulfonated chitosan, 52 2-mercaptobenzothiazole, 53 benzoate, 69 nylon 66, 54 and palm oil; 55 or inorganic clays, such as magnetite clay, aluminium oxide and gamma-alumina. 24,34,56 All of those studies show that composites from PAN give good anti-corrosion performance in both HCl and NaCl environments.…”
