ABSTRACT
Graphene is the most studied and debated material over the last two decades. The optoelectronic and mechanical properties of graphene and its derivatives led graphene research to several scientific fields. This chapter aims to provide an introduction to graphene, starting with the historic developments, all the way to nanotoxicity. A major emphasis on synthesis routes to graphene is discussed and examples relevant to composite science are provided. Subsequent sections describe classifications, nomenclature and characterizations with specific examples of graphene literature. Classification of graphene composites are discussed next as an introduction to the major theme of the book. Finally, the nanotoxicity concerns and considerations are described. We are hopeful that the above-mentioned topics provide necessary foundation for readers to dwell into the following chapters.
