Coleman led scholars from the United States and Ireland to conduct research. They placed crushed graphite into a container, added a "decomposing solution," and then used a machine called a "shear mixer" to stir the graphite and the solution at high speed. The result was the successful production of a large number of tiny graphene flakes, each only 1 nanometer thick and 100 nanometers long, without damaging their structure.
Coleman pointed out: "We have developed a new method to manufacture graphene flakes." The research team later discovered that replacing the shear mixer with a household blender could achieve the same effect. Coleman stated: "We can produce grams in the laboratory alone, but if we scale up, we could produce tons."
