Graphene oxide (GO), due to its large surface area and suitable active sites, is receiving significant attention as a good additive in various coatings due to its excellent chemical resistance, anticorrosion, and high mechanical performances. Furthermore, due to its unique structural dimensions and electrical, thermal, optical, and chemical properties, GO has attracted notable interest in diverse areas, including biomedical and antibacterial applications. This review focuses on the polymer nanocomposite coatings embedded with GO, their synthesis methods, and the role of GO to improve the corrosion protection performance, mechanical and electrical properties, antibacterial application, and thermal conductivity.
