ABSTRACT
This chapter provides a background on graphene, its properties and applications, a brief description of conventional graphene preparation techniques, a discussion on the use of Plasma-Enhanced Chemical Vapor Deposition for the growth of graphene. Graphene is the building block to create carbon nanotubes; for example, a monolayer of graphene rolled up into a cylinder constitutes a single-walled carbon nanotube with a chiral vector and multiple layers of graphene sheets rolled up into a hollow cylinder resemble a multiwalled carbon nanotube. Graphene exhibits interesting electrical, optical, mechanical, and thermal properties. The interesting properties mentioned above have led to the numerous applications such as energy storage devices, transistors, chemical and biosensors, nanoelectromechanical systems, and others, just as it has been with carbon nanotubes previously. The promising applications for graphene are in the construction of a supercapacitor. Graphite consists of graphene sheets held together by weak van der Waals forces that can be broken mechanically or chemically to release individual graphene sheets.
