Plastic That Can Heal Itself?

Apparently so.  From an article at Science magazine:
Materials that heal themselves are going bigtime. Scientists have cooked up a chemical concoction that can patch a 9-millimeter-wide hole in a sheet of plastic, a self-repair orders of magnitude larger than ever demonstrated before. The finding could lead to new kinds of airplane wings and spacecraft components that can repair themselves midflight.

“It’s exciting; I think it’s a big step forward in being able to autonomously heal structures without intervention,” says University of Michigan, Ann Arbor, mechanical engineer Ellen Arruda. She calls the researchers’ scheme “the polymer equivalent of a blood clot.”
