The resulting free-standing rLGO/PVDF-HFP composite thin film revealed excellent electrical conductivity of similar to 3000 S/m and ultrahigh inplane thermal conductivity of similar to 19.5 W/mK at rLGO content of 27.2 wt %. This ultrahigh electrical and thermal conductivity were attributed to the good interfacial interaction, effective chemical reduction, high aspect ratio, and preferential orientation of graphene sheets along the film direction. We believe that our new fabrication procedure can be effectively used for large-scale production and commercialization of conductive composite materials for many thermal and electrical conduction applications.
