Graphene
Graphene is the name given to a two-dimensional sheet of sp2-hybridized carbon. Its extended honeycomb network is the basic building block of other important allotropes; it can be stacked to form 3D graphite, rolled to form 1D nanotubes, and wrapped to form 0D fullerenes. Long-range π-conjugation in graphene yields extraordinary thermal. mechanical, and electrical properties, which have long been the interest of many theoretical studies and more recently became an exciting area for experimentalists. Graphene can be prepared by several approaches such as chemical vapor deposition (CVD), mechanical exfoliation, and chemical reduction of graphite oxide. In the near future, it will be widely used in many fields including energy, electronic, and sensor applications.
