Graphene is a two-dimensional crystal with only one layer of atomic thickness separated from graphite material and composed of carbon atoms. It is the building-block of Graphite, but graphene is a remarkable substance on its own-with a multitude of astonishing properties which repeatedly earn it the title “wonder material”.

The excellent conductivity and light transmission properties of graphene have a very good application prospect in transparent conductive electrodes. Touch screen, liquid crystal display, organic photovoltaic cells, organic light-emitting diodes, etc., need a good transparent conductive electrode material.
