Windows 10: Self-healing glass discovered by accident

Brink · Dec 18, 2017

New type of polymer glass that can mend itself when pressed together is in development by University of Tokyo after a student discovered it.

Japanese researchers say they have developed a new type of glass that can heal itself from cracks and breaks.

Glass made from a low weight polymer called “polyether-thioureas” can heal breaks when pressed together by hand without the need for high heat to melt the material.

The research, published in Science, by researchers led by Professor Takuzo Aida from the University of Tokyo, promises healable glass that could potentially be used in phone screens and other fragile devices, which they say are an important challenge for sustainable societies.

While self-healing rubber and plastics have already been developed, the researchers said that the new material was the first hard substance of its kind that can be healed at room temperature.

“High mechanical robustness and healing ability tend to be mutually exclusive,” wrote the researchers, saying that while some hard but healable materials have been developed, “in most cases, heating to high temperatures, on the order of 120°C or more, to reorganise their cross-linked networks, is necessary for the fractured portions to repair.”

The new polymer glass is “highly robust mechanically yet can readily be repaired by compression at fractured surfaces”.

The properties of the polyether-thioureas glass were discovered by accident by graduate school student Yu Yanagisawa, who was preparing the material as a glue. Yanagisawa found that when the surface of the polymer was cut the edges would adhere to each other, healing to form a strong sheet after being manually compressed for 30 seconds at 21°C...

the start bottom and Cortana not working

Windows has some self-healing capabilities.

E66 camera problem HW or SW?

Sorry to see about your accident!

Hope you heal fast

Anywhow, you will notice that the audio/video is not in sync using the video recorder

My pictures are of very good quality, no stripes

Thanks for posting this read this earlier in week on-line. Should hopefully help those that drop the phone alot

All the best inventions are by accident, aka penicillin.

And many of them at war times.

...when accident is the target...

For sure, war is good...

Some one is going to make a ton of money on this new glass and rightfully so.

I hope the person who discovered it patents it immediately.
And yes amazing on how many inventions were discovered by accident.
