A regular kitchen blender can be used to make graphene flakes

Researchers from England and Ireland's Trinity College developed a method to produce graphene flakes using very simple equipment. The idea is to simply mix powdered graphite with N-methyl-pyrrolidone and then mix it in a blender at high speed. This results in graphene flakes which are about a nanometer thick and 100 nanometer long. This method actually work with a regular kitchen blender!

The researchers say that the blender blades separate the graphite into graphene sheets without damaging the 2D structure. During their experiments, they made several grams of the graphene material, but they say it can be scaled up to produce in ton quantities.

Unfortunately we do not have any technical details on the quality of the actualy produced graphene flakes.
