16.11.2015 Researchers at Lodz university of technology are producing graphene with greater strength
Researchers at Lódz University of Technology developed a novel technology for producing graphene using a metallurgical method. It allows for the production of graphene sheets of higher strength. In the future, the material may find applications in automotive and aerospace industry, electronics and so-called smart garments.
Graphene is a material composed of a single layer of carbon atoms arranged in a hexagonal network. It is over 100 times stronger than steel, has exceptional electrical properties and is impermeable to gas.
Scientists from Łódź have developed the technology to produce graphene with a liquid metallic matrix and carburising gas mixture according to the original, already patented method. They called their product HSMG - High Strength Metallurgical Graphene.
According to scientists from Łódź, , this material, compared to graphene produced using the current methods, has a higher strength and repeatability of the physico-chemical properties under varying pressure and temperature conditions.
Researchers at Lódz University of Technology designed and commissioned a furnace for producing graphene on an industrial scale. It was made by Seco/Warwick, the company with which Łódź scientists have been carrying out the project “Graphene nanocomposite for reversible hydrogen storage”, funded by the National Centre for Research and Development.
The project objective is to create a material that in the future will be used for the production of safe fuel tanks, for example in cars.
Łódź scientists have also established a company whose task is to commercialise the produced graphene.
