Polydopamine/ ۸-Hydroxyquinoline-۵-Sulfonic Acid DopedPolyaniline/Oxidized Multi Walled Carbon NanotubeNanocomposite: Advancing a Formidable Anticorrosion Agent

In this study, multi-stage modification of carbon nanotubes (MWS) with polydopamine (PDA) and polyaniline (PA)were carried out to fabricate a new type of smart corrosion inhibitor nanocomposite. The study investigates theinhibitory effectiveness of ۸-Hydroxyquinoline-۵-Sulfonic acid (۸-HQS) as a novel doping agent, for the controlledrelease of inhibitor at desired pH. Fourier transform infrared spectroscopy (FTIR) was employed to analyze thechemical structure of the synthesized anti-corrosive nanocomposites. Additionally, electrochemical impedancespectroscopy (EIS) was utilized to evaluate the corrosion resistance of the PDA-PA-OMW nanocomposite.
