Scientists create self healing material to be used on smartphones

With this material, if your smartphone falls to the floor and the screen breaks you just have to wait until it automatically regenerates.

Scientists at the University of California (USA) have developed a material that can be used in the fabrication of smartphone screens and can regenerate itself after cracking or scratching.

Scientists conducted several tests on the material, including their ability to regenerate after cracks or scratches. In less than 24 hours the material was able to return to its original shape after being divided into two parts.

The material, which can stretch up to 50 times its original size, is made of a flexible polymer and iodized salt. The material has a different bonding type called ion-dipole interaction, referring to the force between charged ions and polar molecules. This means that when the material breaks or is scratched, the ions and molecules attract to regenerate the material.

A similar material has already been developed and is used in some models of smartphones of last generation, however, it is not able to conduct electricity, so it can not be used in screens, different from this material.


It is believed that the material will be in use in smartphones from 2020. And the future gets more and more interesting.
