Polish scientists find way to make super-strong graphene sheets

Researchers at the Polish Lodz University of Technology developed a metallurgical method for producing graphene, that supplies graphene sheets of superior strength. The method relies on liquid metallic matrix and carburising gas mixture and delivers what the researchers call “HSMG” – High Strength Metallurgical Graphene.

The scientists claim this product has a higher strength and repeatability of the physico-chemical properties under varying pressure and temperature conditions, compared to currently produced graphene. They further explain that since they make graphene on liquid metal (that has a flat surface), the structure continuity is maintained and grants strength.
