Japan Discovered New Glass-like Polymer ‘Polyetherthioureas’, Future of Self Healing Screens

A team of Japanese have discovered a new type of glass that can heal itself from cracks.

Published in the journal Science, a team of researchers from the University of Tokyo have found a hard glass-like polymer called ‘polyetherthioureas‘, that can heal itself with mild and hand pressure.

According to the researchers:
“High mechanical robustness and healing ability tend to be mutually exclusive. 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 repair.”

Their method, however would only require mild (by hand) and a temperature of 21 degrees Celsius (69.8 Fahrenheit). The discovery happened, as many great discoveries do, by accident.

The discovery was made by graduate student Yu Yanagisawa, who thought the material would as a type of glue. He found though, that after he cut the edges of the polymer what remained would stick to itself and form a hardened bond once compressed and heated ever-so-slightly.
