Broken screen is often one of the main causes of smartphone damage. Be careful when you hold it in your hand. Once you accidentally fall to the ground, it will cause irreparable cracks, and you need to spend another sum of money to replace the panel. In the past, many teams have studied this unique screen material, trying to strengthen its toughness or be able to repair itself. Recently, a research team at the University of Tokyo unexpectedly found that an organic compound has self-healing ability, and it can recombine under the ambient temperature of 265438 0 degrees Celsius and continuous illumination for 30 seconds.

The paper published by the research team led by Tian Xiang Zhuo, a professor at the University of Tokyo, was recently published in the American academic journal Science. This paper writes that mechanical strength and elasticity are usually mutually exclusive. At present, hard materials that can heal have been invented, but in most cases, the broken parts need to be repaired by heating, and the high temperature even reaches above 120℃ to reorganize the material structure.

The research team originally intended to develop a new adhesive, but in the process, team member Liu Zeyou unexpectedly found that after the organic compound polyether thiourea was cut, the cut surfaces could still adhere to each other. When he continued to gently press the cutting surface for 30 seconds, the cut polyether thiourea was reassembled into sheets.

Liu Zeyou said that he had to repeat the experiment many times to confirm this discovery, and hoped that this healing glass material could become an environmentally friendly material to avoid throwing away damaged products and generating a lot of garbage.

In the past, many teams have studied unique screen materials. For example, the memory polymer material developed by Motorola uses temperature to achieve self-repair, which means that when the temperature rises, the damaged part will gradually heal; Chemists at the University of California have also developed a new material. When it is scratched or even cut, it can be docked again after about 24 hours at room temperature.
