摘要

Metal materials exposed to the natural environment are prone to damage from temperature, humidity, radiation, and other factors, which can cause corrosion, resulting in economic losses and environmental impacts, and even safety accidents, endangering production and life. Although traditional anti-corrosion techniques can delay corrosion, they suffer from inherent limitations and fail to meet the evolving demands of modern industries. Microcapsule anti-corrosion and self-healing technology, as a new type of intelligent anti-corrosion method, provides a novel solution to address the drawbacks of conventional coatings. This paper summarizes the latest advances in microcapsule anti-corrosion and self-repair technology focusing on its applications in construction engineering, marine engineering, energy facilities and electronic equipment in recent years. It systematically analyzes the structural design of microcapsules, their preparation methods, and the response mechanisms of microcapsule-based systems. Additionally, the current challenges faced by this technology and corresponding solutions are discussed.
