The suggested polybenzoxine@ZrO2 nanocomposite surfaces' excellent anticorrosive feature opens in novel avenues for the creation of high action non-corrosive coatings for variety of sectors. The conclusion of mild steel was decreased as a consequence of the accumulation of PBz-wrapped ZrO2 nanoparticles to the PU coating because they prevented charge transfer at the metal/electrolyte interface. TGA proves that the copolymer matrix's thermodynamic endurance has risen as a result of the ZrO2 NP addition. EIS findings demonstrated coated PU/PBz@ZrO2 nanoparticles' exceptional corrosion prevention ability. According to the results of the TEM/EDX analysis, the corrosion products that form at the metal electrolyte interface function as an inactive coating that slows down the breakdown of metals. Because ZrO2 and PBz work together in harmony, adding polybenzoxazine enhanced ZrO2 nanoparticles to the polyurethane film strengthens its barrier and mechanical features.
