What is Graphene

Graphite comprises two-dimensional sheets of sp2-hybridized, hexagonally arranged carbon atoms — the graphene — that are regularly stacked. The graphene's atom-thin sheets, which form graphite by non-bonding interactions, are characterized by an extremely larger surface area. Graphene shows extraordinary strength and firmness along its basal levels that reach approx. 1020 GPa is almost the strength value of a diamond. Graphene is the basic structural element of some allotropes, including, besides graphite, carbon nanotubes and fullerenes. Used as an additive, graphene can dramatically enhance the electrical, physical, mechanical, and barrier properties of polymer composites at extremely low loadings. (Xu, Suslick 2011). By its properties, graphene is a material of superlatives, thereby promising for industries that produce composites, coatings or microelectronics. Geim (2009) concisely describes graphene as a supermaterial in the following paragraph: By its properties, graphene is a material of superlatives and thereby promising for industries that produce composites, coatings or coatings or microelectronics. Geim (2009) concisely describes graphene as a supermaterial in the following paragraph: Due to these outstanding material's characteristics, graphene is one of the most promising materials and stands in the focus of nanomaterial research. The research group of Hongjie Dai and his colleagues from Stanford University found a technique to prepare nanoribbons. Graphene ribbons are thin strips of graphene that may have even more useful characteristics than graphene sheets. At widths of about 10 nm or smaller, the graphene ribbons' behaviour is similar to a semiconductor as electrons are forced to move lengthwise. It could be interesting to use nanoribbons with semiconductor-like functions in electronics (e.g. for smaller, faster computer chips).
