ABSTRACT
To date, great effort has been made to form uniform graphene films. Graphene films have been prepared by a variety of techniques, including mechanical exfoliation [1-3], graphene in solution [2-5], and epitaxial growth [2,6,7] methods. Mechanical exfoliation produces the highest-quality graphene, which is suitable for fundamental studies; epitaxial growth provides the shortest path to graphene-based electronic circuits, and graphene in solution can offer lower cost and higher throughput for the production of graphene-based nanocomposites as well as larger-size films than other existing methods [2,8]. This chapter describes these methods in detail.
