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

Abstract Sustainable and resilient surfaces are crucial, especially in the petroleum industry, where equipment faces harsh conditions like high temperatures, corrosion, and erosion. These factors often cause material degradation and failure. This paper reviews advancements in self-healing coatings, which able to automatically repair surface corrosion and erosion, improving durability and extending the lifespan of equipment. The focus is on how these coatings reduce operational risks and enhance the long-term performance of industrial components. Erosion and corrosion remain one of the most pervasive and costly challenges 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 review investigates the advancements in self-healing coatings as a promising surface protection strategy. Through an 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 and sustainability. The review focuses on evaluating the efficiency of these coatings under extreme conditions and their compatibility with existing industrial materials, particularly in oil and gas applications. This review highlights the significant progress in self-healing coating technologies for creating sustainable and resilient surfaces. These coatings can autonomously repair surface damage, such as cracks, scratches, and corrosion, restoring their protective properties without external intervention. Both intrinsic and extrinsic healing mechanisms are explored, demonstrating their effectiveness in maintaining surface integrity. However, several challenges remain, including the cost of implementation, the efficiency of healing under extreme 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 such as petroleum sectors. This paper provides an in-depth analysis of the relationship between self-healing performance and the sustainability of surface protection technologies. By focusing on the unique capabilities of self-healing coating, particularly in the petroleum industry, this review addresses how these technologies able to handle the growing demand for environmentally friendly, durable, and resilient surface solutions. Additionally, it identifies future research directions aimed at improving cost-effectiveness, enhancing healing efficiency under extreme conditions, and ensuring broader industrial applicability of these coatings to support sustainable development goals.
