Self-healing materials have been extensively explored in metal anti-corrosion fields. However, improving the self-healing efficiency remains a significant work that severely limits their further development. Here, a strategy to fabricate anti-corrosion coatings with efficient self-healing properties based on microfluidic electrospinning technologies and UV-curable healing agents is reported. The damaged composite coating contains core-shell nanofibers that can be completely healed within only 30 min, indicating an outstanding healing efficiency. The corrosion current density (I
