摘要

The long-term performance of infrastructure, such as bridges, buildings, and dams, depends on the durability of the materials used in construction. Metal-organic frameworks (MOFs) play a critical role in enhancing material resilience, particularly against corrosion, a significant factor in structural degradation. This review attempts to systematically evaluate recent studies that assess the integration of MOFs with traditional materials under varying environmental stressors, including temperature extremes, chemical exposure, and soil conditions. The review combines exploratory information gained through referenced experimental and computational findings on MOF-based coatings applied to construction substrates, such as steel and concrete. Key parameters analyzed include porosity, thermal stability, ion-exchange capacity, and corrosion inhibition efficiency. Comparative studies with traditional anti-corrosive systems have reported cases where electrochemical impedance spectroscopy showed an approximately threefold increase in charge transfer resistance, indicating superior barrier properties. Additionally, surface analysis studies demonstrated up to 50% less mass loss and improved morphological stability after thermal cycling and chemical exposure. Research has proven that structures built with MOF-enhanced materials demonstrate up to 65% increased resistance to corrosion in adverse conditions, such as chloride-rich environments. Reports on electrochemical tests revealed a 40–60% reduction in corrosion rate, while surface analysis showed improved retention of the morphological features under thermal cycling. Further, qualitative findings suggest that the mode of protection offered by MOFs is mainly mediated through selective adsorption and barrier formation. These results highlight the potential of MOFs as sustainable additives for extending the lifespan of infrastructure in the modern construction industry.
