Graphene, a one-atom thick planar sheet of sp2 bonded carbon atoms packed in a honeycomb lattice, is considered to be the mother of all graphitic materials like fullerenes, carbon nanotubes, and graphite. Graphene has created tremendous interest to both physicists and chemists due to its various fascinating properties, both observed and predicted with possible potential applications in nanoelectronics, supercapacitors, solar cells, batteries, ﬂexible displays, hydrogen storage, and sensors. In this paper, a brief overview on various aspects of graphene such as synthesis, functionalization, self-assembly, and some of its amazing properties along with its various applications ranging from sensors to energy storage devices had been illustrated.
Since the discovery of fullerene (C60 ) in 1985 by Kroto and his coworkers , several novel carbon nanomaterials have been isolated. In 1991, carbon nanotube (CNT) was discovered by Iijima , while graphene, a two-dimensional form of graphite, was isolated in 2004 by Novoselov et al. of Manchester University, UK . Graphene has become a new supermaterial due to its unique physical properties. This new kind of two-dimensional carbon nanostructure has attracted tremendous attention both...
