Polypyrrole PPy nanocomposites incorporating different carbon nanostructures CNSincluding graphenes of different sizes, carbon nanofibers CNFs and carbon nanotubes CNTshave been successfully synthesized using a surface initiated polymerization SIP method. The effects of graphene size, loading level and surface functionality on the electrical conductivity and dielectric permittivity of their corresponding nanocomposites have been systematically studied. The electron transportation mechanism has been investigated, which follows a quasi 3-d variable range hopping VRH behavior in the nanocomposites.
