۸-Hydroxyquinoline-۵-Sulfonic Acid/Zinc-Doped Polyaniline Nanocompositein Epoxy: A Robust Solution for Anticorrosion and Self-Healing Applications

Uncontrolled leaching of corrosion inhibitors from coatings can cause environmental pollution andreduce anticorrosion effectiveness. To address this, we developed a novel nanoscale additive usinghydroxyquinoline-۵-sulfonic acid-doped polyaniline (HQPA). Our study shows that this innovativeagent enhances polyaniline dispersion and reduces leaching, resulting in superior anticorrosionperformance. Steel coated with an epoxy containing HQPA has a corrosion rate about ۴۱ times lowerthan those with non-conjugated inhibitors. These findings highlight the potential of polymercorrosioninhibitor conjugates in commercial coatings, offering robust corrosion protection whilebeing environmentally responsible.
