Scientists invent phone screen material that heals itself.

Having a broken or cracked screen is a major problem faced by smartphone users whether its an iphone or low end price android.

researchers from the university of california have invented a material that can heal itself when torn or broken.

when torn, the material heals itself under 24 hours.

The material used in conducting this is made of an ionic salt and a stretchable polymer that has a special type of bond called an ion-dipole interaction which is a force between charged ions and polar molecules. The charged ions and polar molecules attract themselves to heal the your screen each time its broken. 

wang, the chemist leading the research, predicts that by 2020, the self healing material will already be used for phone screens and batteries.
