The excellent anti-corrosive property of the suggested Polybenzoxazine (Silane functionalized Benzoxazine- Polyurethane- Zirconium doped Copper Oxide Nanoparticles) nanocomposite coating material surfaces opens up new possibilities, to development highly effective non-corrosive coatings for a number of industries. The aggregation of the Polybenzoxazine wrapped Zirconium doped Copper oxide Nanoparticles to the Polyurethane reduce the strength of mild steel because they hindered charge transfer metal as well as electrolyte contact. UV, FT-IR, and XRD techniques were used to initially characterise the created nano-coating materials. In accordance with the findings of the SEM-EDX investigation, the products of corrosion at the surface of the metal electrolyte contact act as an inert conversation that inhibits metal degradation
