This review presents the corrosion resistance of epoxy coatings containing TiO2 nanotubes and BTA (benzotriazole)-modified TiO2 nanotubes. The purpose of the study is to examine how effectively these materials protect against corrosion on metal surfaces in various environments. The synthesis of TiO2 nanotubes and BTA/TiO2 nanotubes in epoxy coatings offers a promising approach to significantly enhance corrosion resistance while also opening considerable potential for applications in industries requiring high durability and material protection.
