ABSTRACT

Smart polymer coatings have emerged as a revolutionary technology in surface engineering, combining self-healing and stimuli-responsive features to prolong material lifetimes and boost performance. This review thoroughly investigates recent developments in smart polymer coatings, concentrating on mechanisms such as microencapsulation, reversible covalent bonding, and dynamic crosslinking that facilitate self-repair after damage. Furthermore, the article examines coatings that react to environmental stimuli including temperature, pH, light, and mechanical stress thereby modifying their properties in real-time. Essential materials discussed include cutting-edge polymer formulations enhanced with nanoparticles, microcapsules, and various functional additives
that enhance durability and reactivity. A comparative analysis of different fabrication methods, such as layer-by-layer assembly, 3D printing, and advanced deposition techniques, underscores the vital role of processing parameters in fine-tuning coating microstructure and effectiveness. Principal findings reveal that these smart coatings not only significantly enhance the service life and
dependability of protective surfaces in extreme environments but also present promising applications in aerospace, automotive, biomedical, and smart device sectors. Future research is set to tackle scalability, environmental sustainability, and the incorporation of digital monitoring systems for real-time performance evaluation.
