Graphene can be made in the kitchen

Graphene is the thinnest and toughest material in the world, but it has been considered difficult to produce in large quantities. Coleman, a professor of chemical physics at Trinity College in Dublin, Ireland, found that the kitchens of ordinary people have the ability to convert graphite into graphene, which means that the ability to produce graphene is expected to increase further.

Coleman led scholars from the United States and Ireland to conduct research. They put some broken graphite into a container, added "decomposing melt", and then put graphite in a machine called "shear mixer". And the melt stirred at high speed. As a result, the graphite can be successfully stirred into a large number of fine graphene sheets, each of which is only 1 nanometer thick and 100 nanometer long without destroying its structure.

Coleman pointed out: "We have developed a new method to make graphene sheets." The research team later found that the same effect can be obtained by replacing the shear mixer with a home mixer. Coleman said: "Single production in the laboratory, we can produce a few grams, but if you increase the scale, it will be enough to produce tons of dollars.
