Abstract:

The self-repairing anti-corrosion coatings is a type of advanced special functional coatings that can realize automatic repair of minor coating damage, providing long-term corrosion protection function for metals. In recent years, although the research on the self-repairing anti-corrosion coatings in the field of coatings has attracted much attention, there is still insufficient detailed classification and in-depth exploration of it, which to some extent limits the comprehensive understanding of its function and application potential. This manuscript provided an in-depth analysis of the operating principle of the self-repairing anti-corrosion coatings, elaborated on its diverse types, and systematically reviewed the research achievements in this field. While affirming its ability to achieve continuous coating integrity and significantly improve corrosion resistance, it also pointed out potential defects in current coatings such as low self-repairing efficiency and high requirements for self-repairing conditions. In response to these issues, this article proposed a series of optimization suggestions, hoping to provide valuable references for the future development of coating technology. With the continuous progress of technology, the self-repairing anti-corrosion coatings was expected to play a more important role in automotive manufacturing, marine engineering, hydropower and nuclear power, and other fields, providing solid guarantees for the long-term and stable anti-corrosion protection of metal substrates, and promoting the sustainable development of related industries.
