CORROSION PROTECTION STRATEGIES FOR METALS USING NANOMATERIALS AND COATINGS

Abstract

Corrosion poses a significant challenge to the durability and efficiency of renewable energy systems, including solar panels, wind turbines, and geothermal installations, which are often exposed to harsh environmental conditions. To address this issue, advanced nanomaterials and innovative coatings have emerged as promising solutions, offering superior protection through enhanced barrier properties, self-healing mechanisms, and environmental sustainability. Nanomaterials such as graphene, Carbon Nanotubes (CNTs), and nanoceramics reinforce coatings with exceptional mechanical strength and corrosion resistance, while smart coatings with embedded microcapsules or stimuli-responsive polymers enable autonomous damage repair. Furthermore, hybrid nanocomposite coatings combine organic and inorganic components to improve UV resistance, hydrophobicity, and electrochemical stability. The integration of IoT-enabled sensors within these coatings allows for real-time corrosion monitoring, enabling predictive maintenance and minimizing downtime. Sustainable alternatives, including bio-based and chromate-free coatings, are also gaining traction to meet stringent environmental regulations. This review explores the latest advancements in nanomaterial-enhanced corrosion protection strategies, highlighting their potential to extend the lifespan, reduce maintenance costs, and enhance the reliability of renewable energy infrastructure. By leveraging these cutting-edge technologies, the renewable energy sector can achieve greater operational resilience and support the global transition toward sustainable energy systems.
