Innovation for film unemployment--self-healing smart phone with broken screen

With the increasing proportion of smartphone screen, full screen mobile phone has become a trend, although the large-screen smart device can bring us a good experience, but the chance of screen wear and fragmentation increases. Many glass bodies in the daily use of the process will appear in a variety of large and small scratches, if accidentally dropped to the ground, there is the possibility of a broken screen, and the change screen is more expensive, changed friends must have deep experience.

It is reported that researchers at the University of California have devised a self-healing material that is expected to fundamentally address the screen scratches on mobile phones. This stretchable ionic salt polymer, because of the special ions and molecules attracted to each other, so that can achieve self-healing function. It is learnt that the repair ability of this material is not limited to scratches. When it is divided into two halves, it can be repaired and connected autonomously within 24 hours, and it is still not separated in the case of stretching to 50 times times the original size. And the key is the chemical bond between the molecules. The material found is the world's first self-healing material that can be applied to touch screens, and is expected to be formally entered into consumer electronics in 2020.

The team's head of research and Development, Chao Wang, explains the phenomenon, where a covalent bond occurs between the chemical bonds between the two materials, and the bonds are more firmly connected to each other, rather than covalent bonds that are relatively easy to separate. For example, the connection between hydrogen and oxygen, despite being constantly separated and broken, but still can form a flow of water. The entire development team developed the effect of self-healing through the forces of even Ionic bond, charged ions, and polar molecules. Flexible polymers combine the ionic salts closely together and even become an integral effect.

It is important to note that "light" may play a crucial role in this technology. A professor at the University of Bristol in the UK said: "When your phone screen is scratched, you can place your phone in the sun in the window and the scratches on your phone will probably be self-repairing after 24 hours." In other words, if the technology is applied to the actual, after the phone screen damage, you can not send to the mobile phone shop to repair, as long as the sun can be cured.

Self-healing materials have always been the focus of scientific research and search, in addition to the repair of electronic equipment, self-healing materials can be widely used in medical, military and wearable devices and other fields. This kind of interesting and powerful material can provide great help for the further development of science and technology, although the self-healing material seems to be far from the real application, but with the progress of technology, it is very possible to realize large-scale application. "Basically within three years, products with self-healing capabilities will enter the market and affect our daily lives," Wang said. Especially for smartphone products, the technology will be higher than the present. ”

According to developments in the field of self-repairing materials, self-healing materials are expected to become commercially available in a few years. There is no denying that self-repairing materials still have problems and improved space, but these problems are expected to be cracked, self-repairing materials in a few years to apply to the actual scene can be expected.
