Chemistry

Self-Healing Polymers for Autonomous Crack Repair in Structural Coatings

Quick fact

Some self-healing polymers use microcapsules filled with a healing agent; when a crack forms, the capsules break, releasing the agent that flows into the crack and polymerizes, restoring up to 90% of the material's original strength.

Why this is interesting

Imagine a scratch on your car's paint that heals itself overnight, just like a cut on your skin. What if materials could mend their own cracks without any human intervention?
