Self Healing Glass Discovered for Smartphones that Fixes its Own Cracks
Japanese researcher have developed a new glass that can heal itself from crack and breaks. Thus self healing glass is made up of polyester thioureas can heal breaks when pressed together by hand. It means now you don’t need to heat screen to melt material. Self Healing Glass Discovered for Smartphones that Fixes its Own Cracks.
This research is published in Science, ensured self healable glass that can potentially be used in phone screens and other fragile devices. It should be noted here that self healing rubber and plastics are already developed.

The new glass is very robust and can be quickly prepared by compression at fractured areas. The self healing property of this glass was discovered accidentally by a graduate student Yu Yanagisawa, who was preparing the material as a glue.
The researcher wrote in a statement:
“High mechanical robustness and healing ability tend to be mutually exclusive. 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 reorganize their cross-linked networks, is necessary for the fractured portions to repair
The new glass is very robust and can be quickly prepared by compression at fractured areas. The self healing property of this glass was discovered accidentally by a graduate student Yu Yanagisawa, who was preparing the material as a glue.
He realized that when the polymer glass surface was cut the edges joined each other. He compressed in for 30 seconds at 21°C. Further experiment revealed that healed material regained its original strength after few hours.
