    Abstract
    The study of polyurethane-based multifunctional coatings for steel protection in the oil and gas sector is the focus of this thesis. Polyurethanes are versatile polymeric materials with excellent wear resistance, superb thermophysical and elastic properties, and exceptional operating capabilities in the oil and gas sectors. Following an overview of the developments in PU coatings, including novel additives and self-healing processes, the study concentrates on two cutting-edge systems. By dispersing TiO₂ nanoparticles uniformly, the first technique improves barrier qualities and corrosion resistance of PU coatings using a graphene oxide-titania (GO-TiO₂) composite. In the second system, PU coatings enhanced with TiO₂ are combined with MS30, a green corrosion inhibitor. Electrochemical and salt spray studies validate that these formulations achieve 99.9% efficiency, a significant improvement in corrosion inhibition. The results show that these innovative PU-based coatings provide steel with outstanding protection, prolonging durability in challenging conditions, especially in oil and gas applications.
