Graphene oxide (GO) is the oxidized form of graphene. It is a single-atomic-layered material that is formed by the oxidation of graphite which is cheap and readily available. Graphene oxide is easy to process since it is dispersible in water and other solvents. Due to the oxygen in its lattice graphene oxide is not conductive,…

Graphene and graphene oxide have attracted tremendous interest over the past decade due to their unique and excellent electronic, optical, mechanical, and chemical properties. This review focuses on the functional modification of graphene and graphene oxide. First, the basic structure, preparation methods and properties of graphene and graphene oxide are briefly described. Subsequently, the methods…

Currently, a number of techniques are used to produce graphene and these include epitaxial growth, chemical vapour deposition (CVD), and thermal or mechanical exfoliation. Large scale production of graphene can also be effectively realized through chemical reduction of graphene oxide. Since graphene was first reported in 2004, made using mechanical exfoliation from graphite, graphite oxide…

AbstractThanks to their remarkable mechanical, electrical, thermal, and barrier properties, graphene-based nanocomposites have been a hot area of research in the past decade. Because of their simple top-down synthesis, graphene oxide (GO) and reduced graphene oxide (rGO) have opened new possibilities for gas barrier, membrane separation, and stimuli-response characteristics in nanocomposites. Herein, we review the…

AbstractGraphene has attracted great interest for its excellent mechanical, electrical, thermal and optical properties. It can be produced by micro-mechanical exfoliation of highly ordered pyrolytic graphite, epitaxial growth, chemical vapor deposition, and the reduction of graphene oxide (GO). The first three methods can produce graphene with a relatively perfect structure and excellent properties, while in…

Graphene, the atom-thick carbon materials, acts as a superconductor when two sheets are layered at a selected angle. Credit score: […]

Image Credits: ivan_kislitsin / Shutterstock.com Graphene is a unique form of carbon that is one atom thick; so thin that it is essentially considered two dimensional. Graphene has shown significant promise for water filtration applications and a team of scientists from Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia recently developed an extremely efficient…
