Graphene (/ËÉ¡raef.ËÉ¡rÃ¦f/) iËn is an allotrope of carbon in the form of a-two, dimensional-atomic, scale hexagonal lattice in which one atom forms each. Vertex it is the basic structural element of other, allotropes including, graphite, charcoal carbon nanotubes and. fullerenes
Strong and Porous. For years, researchers have known that carbon, when arranged in a certain way, can be very strong. Case in point: graphene. Graphene, which was heretofore, the strongest material known to man, is made from an extremely thin sheet of carbon atoms arranged in two dimensions. But thereâs one drawback: while notable for its thinness and unique electrical properties, itâs very difficult to create useful, three-dimensional materials out of graphene.
