Scientists invents a material to help smartphone-screen repair its

A group of Chemists at the University of California, Riverside, have invented a new self-healing smartphone display material that is able to heal itself. Take for instants, you drop and shatter your smartphone screen, instead of buying a new screen or replacing the phone, the material automatically help repair the damage screen. Isn't that nice?

The material is made of a stretchable polymer and an ionic salt, and for test conducted it was found that the material has a self-healing capabilities.Also when the material was subjected to tearing, it took less than 24 hours for it to stitch itself back together.

This miraculous self-healing is due to the presence of ion-dipole interactions – a unique type of bond found within the material. The bond is resultant from an electrostatic attraction between charge ions and polar molecules. The attraction force created between the molecules and ions work to fill in voids created by tears or cracks in the display.

Although self-healing materials may have been around for a while now, what makes this one special it is the first capable of conducting electricity, which makes it perfectly suitable for smartphone displays.

According to Chao Wang, one of the scientists leading the research, self-healing smartphone displays won’t become commercially available right away but he believes that they’ll begin showing up on smartphones by 2020.

So when next you damage the screen of your mobile device, you won't have to worry about replacement since it will be capable of repairing itself.
