As graphene itself is ideally only one-atom-thick and formed from hexagonally connected carbon atoms. These share a single electron with three other carbon atoms which leave one electron free for adequate electrical conductivity. It is black in color, where the thickness is around 3-4 nanometers with the lateral dimension is 5 to 10 microns. There is 4 to 6 number of layers in the research grade graphene nanopowder. It has a high aspect ration, about 1000 times greater than the 99% of carbon.
