Dramatic reduction in corrosion of a steel plate coated with a self‐healing coating (right) as compared to a conventional coating is demonstrated. Two samples were scratched and placed in 5% NaCl for 5 days. The background is an optical image (2× magnification), in the foreground is an SEM image of the scratch. In the self‐healing sample, the scratch has almost completely self‐healed, while in the control sample, the scratch remains all the way down to the substrate, as reported by Paul Braun and co‐workers on p.645 .
