A Review on Self-Healing Coatings Technologies for Sustainable and Resilient Surfaces

Sustainable and resilient surfaces are crucial, especially in the petroleum industry, where equipmentfaces harsh conditions like high temperatures, corrosion, and erosion. These factors often cause materialdegradation and failure. This paper reviews advancements in self-healing coatings, which able toautomatically repair surface corrosion and erosion, improving durability and extending the lifespan ofequipment. The focus is on how these coatings reduce operational risks and enhance the long-termperformance of industrial components. Erosion and corrosion remain one of the most pervasive and costlychallenges across various industries, with significant economic and environmental impacts. To combat this,corrosion protection is crucial in shielding equipment from the harmful effects of corrosion. This reviewinvestigates the advancements in self-healing coatings as a promising surface protection strategy. Throughan extensive analysis of recent research, this paper explores the mechanisms of intrinsic and extrinsic self-healing coatings, their ability to repair surface damage, and their ability to enhance materials’ resilience andsustainability. The review focuses on evaluating the efficiency of these coatings under extreme conditionsand their compatibility with existing industrial materials, particularly in oil and gas applications. Thisreview highlights the significant progress in self-healing coating technologies for creating sustainable andresilient surfaces. These coatings can autonomously repair surface damage, such as cracks, scratches, andcorrosion, restoring their protective properties without external intervention. Both intrinsic and extrinsichealing mechanisms are explored, demonstrating their effectiveness in maintaining surface integrity.However, several challenges remain, including the cost of implementation, the efficiency of healing underextreme environmental conditions, and the integration of these coatings with existing industrial materials.Despite these obstacles, self-healing coatings offer substantial potential to extend equipment lifespan and reduce maintenance costs, making them an asset for industries, especially in high-risk environment suchas petroleum sectors. This paper provides an in-depth analysis of the relationship between self-healingperformance and the sustainability of surface protection technologies. By focusing on the unique capabilitiesof self-healing coating, particularly in the petroleum industry, this review addresses how these technologiesable to handle the growing demand for environmentally friendly, durable, and resilient surface solutions.Additionally, it identifies future research directions aimed at improving cost-effectiveness, enhancinghealing efficiency under extreme conditions, and ensuring broader industrial applicability of these coatingsto support sustainable development goals. © 2025, Offshore Technology Conference.
