Abstract

Graphene is the name for a monolayer sheet of carbon atoms that are bonded together in a repeating pattern of hexagons. This sheet is only one atom thick. Monolayers of graphene stacked on top of each other. In this article, we have compared the characterization results of graphene and graphene oxide along with synthesis via different methods. A sigma bond connects each atom in a graphene sheet to its three closest neighbours and each atom also contributes one electron to a conduction band that covers the entire graphene sheet. Graphene when oxidized is called graphene oxide (GO) and is mostly used in photoelectric, materialistic, catalyst and energy fields due to its thermal, electrical and mechanical characteristics. It is also used in the field of medical science, drug delivery and biomedical applications. Graphene have been improved due to import of 3D printing technology. In last few years, graphene has taken the attention of most material science researchers due to its various applications. Graphene based polymers and nanocomposites are widely used in sensors, optoelectronics, magneto transport, automotive, biosensors, electronics and aerospace fields.

Keywords
