Abstract

The discovery of graphene and graphene based polymer nanocomposites is an important addition in the area of nano-science, playing a vital role in modern technology and science. To overcome the shortcomings of carbon based nano-fillers such as a carbon nanotubes graphene is an important discovery. Carbon nanotubes have proven very good conductive fillers but the main drawback of carbon nanotubes is its high production cost. Graphene is modified with oxygen and nitrogen with functional groups. Thus, graphene is nothing else than a single layer of graphite. The main goal of the researchers is to develop graphene, very thin carbon sheet with hexagonal network and study the highly controlled growth method and synthesis of graphene by hummer method. This study describes the literature review of graphene, graphene oxide and synthesis by hummer method is comparatively better than other variant of graphene oxide.
