Tokyo University polyether thiourea developed from the glass
Kailin Chem News can join two halves of glass together without adhesives, sounding an impossible task. Researchers at Tokyo University in Japan found that if the material used to make the glass is polythiourea, it would be easy to do it.
Japanese news site "Rockets News" reported on the 16th, the researchers originally planned to develop new adhesives, but occasionally found that polyether thiourea compounds with self-healing properties.
Researchers say that if a glass made of polythiourethiourea breaks down, the glass will self-repair the cracks as long as the broken part is closed at room temperature and a little pressure is applied for a while, and the firmness remains the same. The video provided by the University of Tokyo showed that a piece of polythiourea semitransparent glass, 20 mm long, 10 mm wide and 2 mm thick, was split into two pieces. The researchers tweened the two parts with tweezers and held them in close contact for a while. The two parts The glass is joined together, followed by a 300g weight with a clip.
The findings are published in the latest issue of Science.
