Fluid-Inspired Self-Healing Coating

Feb-02-19 A self-healing coating that patches cracks in seconds could help prevent corrosion damage to metal structures.

Although most metal structures are treated with an anti-corrosion coating, that coating can be damaged by scratches or cracks—exposing the metal to damage. To help prevent this, the team from Northwestern University created an oil-based coating able to flow back together and self-repair in just seconds. Microscopic graphene capsules added to the coating ensure the material is thick enough to remain on the metal in harsh conditions, while still being able to heal repeatedly when scratched, even after 200 scratches in the same location.
