Scientists at the University of Califonia, in Riverside, United States, developed a compound of elastic polymers and ionic form salts that will allow the screens of cell phones to self-repair.
The feared scratches on mobile screens may have been counted for days.
The researchers carried out various tests with the material, including the ability to repair small cuts and scratches, also mention that after breaking the material in half, it was able to automatically sew itself in less than 24 hours.
The team explains that the material, which can stretch up to 50 times its original size, is constructed of a stretched polymer and ionic salt. In addition, it has a special type of bond, which makes these reactions possible, according to Chao Wang, the chemist leading the research.
This material works because the negative poles of the molecules attract the positive ions and the positive poles attract the negative ions, that is to say, the parts of each molecule are united by the forces of the opposite charges. This means that when the material breaks or has a scratch, the ions and molecules attract each other to repair the compound.
This is the first time that science has created a material that is self-repairing and able to conduct electricity, which makes it especially useful for the use of screens of mobile phones, tablets and batteries.
The team will present the research at the American Chemical Society, the world’s largest scientific organization dedicated to the study of chemistry, in the coming days. If the material is able to achieve what it promises, Wang predicts that it will be able to be used on all phones from the year 2020.
