The simplest way to describe graphene is that it is a single, thin layer of graphite — the soft, flaky material used in pencil lead. Graphite is an allotrope of the element carbon, meaning it possesses the same atoms but they’re arranged in a different way, giving the material different properties. For example, both diamond and graphite are forms of carbon, yet they have wildly different natures. Diamonds are incredibly strong, while graphite is brittle. Graphene’s atoms are arranged in a hexagonal arrangement. 

Function:
(1)Lower percolation value than that of conductive carbon black.
(2)Easy to be processed and dispersed with ultra-thin planar structure.
(3)1-3% addition is suggested for conductive coatings.
(4)Can be used as additives in cathode or anode of lithium ion battery to increase the battery’s capacity, cycling life and rate retention.
(5)Can be integrated to prepare the thermal conductive composites and thermal radiation coatings.

Application Area:
Graphene has attracted more and more attention from scientists in diverse areas , because it has exhibited potential applications in microelectric devices, sensors, biomedicines and mechanic resonators.
