Electrical Properties of a Graphene-based Polymer Nanocomposite.

A polymer/CMG (chemically modified graphene) composite has been prepared by a solution-based processing technique followed by hot pressing or injection molding to prepare continuous sample specimens. The electrical properties of these composites have been measured by 2- and 4-probe techniques, as a function of temperature and concentration to investigate the mechanisms by which electrical transport occurs in a composite with single graphene sheet filler material, and the percolation threshold at which conduction occurs.
