The chemists who led the study said that after they tore the material in half, the materials would automatically come together within 24 hours. The researchers performed a number of tests on the material, such as cutting, scratching, etc., to prove their self-healing ability.
It is reported that the material is made of a stretchable polymer and an ionic salt and can be stretched to 50 times its original size. Due to the special chemical nature of the material, ions and molecules attract each other to heal the material when it is broken or scratched.
This is the first time scientists have created self-healing materials that are electrically conductive. This material is especially suitable for the manufacture of mobile phone screens and batteries. It is understood that some LG phones have used similar materials on their backs to automatically cure scratches, but this material is not conductive, so manufacturers cannot use it to make screens. Because most mobile screens have an electrode grid hidden, when you touch it, the finger and the screen complete a circuit that tells the phone what to do.
According to scientists, by 2020, this new self-healing material can be used in the manufacture of mobile phone screens and batteries.
