    • Abstract


      In this research study, halloysite nanotubes (HNTs) were applied as nanocontainers to encapsulate the synthesized 3,4$^{\prime}$-dihydro-3-[2$^{\prime}$-mercaptothiazolidine]indol-2-one (DMI) molecules for corrosion protection of carbon steel in a 3.5% NaCl solution. Fourier transform infrared analysis was used to prove the loading of HNTs with DMI. Poly(ethylene-co-acrylic acid) and branched polyethylenimine polyelectrolyte layers were deposited on the surface of DMI-loaded HNTs by a layer by layer (LbL) method. The LbL deposition technique was verified by a zeta potential test. Release of DMI corrosion inhibitors from HNTs in alkaline pH was verified by using UV–visible spectroscopy results. Electrochemical impedance spectroscopy technique was applied to consider the anticorrosion ability of 1, 2.5 and 5 wt% DMI-loaded HNTs as smart epoxy coatings.
