# chem: it can self-repair by capturing carbon from the air

<< A material designed by MIT chemical engineers can react with carbon dioxide from the air, to grow, strengthen, and even repair itself. The polymer, which might someday be used as construction or repair material or for protective coatings, continuously converts the greenhouse gas into a carbon-based material that reinforces itself. >>

<< Materials science has never produced anything like this (..) These materials mimic some aspects of something living, even though it's not reproducing. >> Michael Strano
