No more broken phone screens? Japanese student accidentally discovers self-healing glass material

No more broken phone screens? Japanese student accidentally discovers self-healing glass material

That might sound like it could be an incredible breakthrough when it comes to cracked screens but questions still remain if it would be as responsive as other phone screens out there and if under screen fingerprint sensors would work through this material. Luckily, we are making advancements in phone screen technology to prevent the breaking from occurring in the first place as well as now a much more possible solution, self-regenerative phone screens. The new "glass", polyether-thioureas, was discovered as the researchers were testing new adhesives. The researchers quickly discovered the finding could be used in displays and chose to work more on it to see how useful it could be in the real world.

The groundbreaking new material could lead to virtually unbreakable phone screens.

Researchers have developed a form of glass capable of repairing itself after shattering, in what could be a significant breakthrough for the smartphone industry.

"I hope the repairable glass becomes a new environment-friendly material that avoids the need to be thrown away if broken", Yu told NHK, adding that he repeated the experiment several times to confirm his findings.

As far-fetched as it may seem, scientists have been toying around with the idea of self-repairing smartphone screens for a few years now, but only a few devices, such as the curved LG G Flex 2, have taken these substances seriously.

In general the polymer is "highly robust mechanically yet can readily be repaired by compression at fractured surfaces". "In most cases, heating to high temperatures, on the order of 120 degrees Celsius or more, to reorganize their cross-linked networks is necessary for the fractured portions to fix".

That's a big difference from other materials which have needed high heat to heal themselves. Instead, the researchers say that it usually takes about two hours for the polymer to fully fix itself and regain its original strength.
