Mobile phone screen material capable of conducting electricity and self repairing scratches

If you accidentally drop your phone and wear out the screen, you usually have only two choices: either repair it or replace it with a new phone.
A third option is offered by a group of chemists at the University of California, riverside, who have invented a mobile phone screen material that can self repair scratches.
The researchers conducted a variety of tests on the new material, including its ability to repair cuts and scratches. They cut the material in half and it took them only 24 hours to reconnect.
This material also has strong ductility and can be stretched to 50 times its original size. This material is composed of a malleable polymer and an ionic salt. It forms a special adhesive force, which is also called ion dipole interaction. It is a force between charged ions and polar molecules. This means that when the material breaks or scratches, the charged ions and polar molecules in the material will attract each other, so as to achieve the purpose of repair.
This is the first time that scientists have developed conductive self-healing materials, especially suitable for mobile phone screens and batteries.
Some LG phones, such as G flex, have used a similar material on the back cover, so the back cover of those phones can also repair scratches. But those materials cannot conduct electricity and cannot be used to produce mobile phone screens. Most mobile phones have an electrode network at the bottom of the screen. When you touch the screen, your fingers can form a complete circuit with them to operate the mobile phone.
Researchers predict that this self-healing material can be used to produce mobile phone screens and batteries by 2020.
The R & D team behind this new material has presented their research results at the meeting held by the American Chemical Society on April 4. Wang Chao, a chemist who led the R & D team, said: "self repairing materials seem to be far from practical application, but I believe they will be applied to mobile phones soon. There will be many self repairing products in the next three years, which will change our daily life. They will give our mobile phones better performance."
