ABSTRACT

Graphene is a form of carbon with an hexagonal structure and one atom thickness. Geometrically, if graphene is bent, it could be considered as a base structure for constructing other important carbon nanomaterials, such as nanotubes and fullerenes. Following the isolation and extraction of graphene in 2004, the study of the electronic properties of graphene has intensied and researchers have proposed modications and new experimental arrangements. The nature of the modications can be structural or chemical, such as the presence of vacancies and doping with atoms and molecules. This chapter discusses how the defects and alkaline functionalization on graphene can modulate its physical and chemical properties.
