Researchers design self-healing material

Scientists from all over the world have been working on materials for years that could repair themselves after damage. They have already created several such technologies, but a much more interesting project has been developed by a team of researchers from the University of Michigan, which has just been presented in the action.

NASA-sponsored research has allowed the creation of a material that, after piercing, for example, within a few moments, will self-seal the hole and harden it to such an extent that the strength of the damage will not be different from the rest.

The secret of this technology is the liquid substance between the two layers of solid material that hardens when exposed to oxygen. When the material is punctured, the substance leaks to the surface and, thanks to oxygen, hardens within a fraction of a second, completely blocking the opening. Although similar repair methods have been used with special light-cured capsules, the new method is definitely faster.

This solution can be ideal for the International Space Station, protecting astronauts from micrometeoras that can pierce the plating. It will also be useful in future space missions, protecting ships from destruction.
