Corrosion is a severe issue in the effective utilization of metallic components and structures in industrial and coastal zones. Worldwide, substantial efforts have been dedicated to developing corrosion mitigation approaches. Among the different corrosion prevention methods, protective coatings are proven to be more effective in aggressive environments. Epoxy is a thermosetting polymer with unique chemical resistance, thermal stability, and mechanical integrity. The incorporation of different polymers in the epoxy matrix has motivated extensive research progress in the field of corrosion protective coatings. Epoxy matrix reinforced with polymer and nanofiller has resulted in improved adhesion, wear, barrier, and anti-corrosion properties of the nanocomposite coatings. Corrosion protection performance of a nanocomposite depends on nanofiller dispersion, physical and covalent interaction between matrix/nanofiller, and nanofiller adhesion to the substrate. Design and formulations of epoxy blend-based nanomaterials may enable appropriate tailoring of the overall performance of the resulting anti-corrosion coatings for advance technical applications, including aerospace, automotive, construction, and electronic devices. New formulation techniques can overcome challenges toward high-performance future epoxy-based coatings. This presentation is keen on updating the development, processing, and formulations of epoxy-based anti-corrosion coatings.
