High electrical performances of polytetrafluoroethylene composites containing few-layer graphenes are established by solid-state processing. Polytetrafluoroethylene and FLG powders are mechanically mixed without solvents at room temperature, and hot-pressed. Few-layer graphenes are attached to the polytetrafluoroethylene powder, and gradually wrap the powder surface during milling with a low milling speed. The few-layer graphene-wrapped polytetrafluoroethylene powders readily facilitate the formation of a continuous few-layer graphene network due to the contact between adjacent few-layer graphene-wrapped powders. The final composites using few-layer graphene-wrapped polytetrafluoroethylene powders include a three-dimensional conducting network. Eventually, the wrapping morphology of the polytetrafluoroethylene/few-layer graphene powder results in a remarkable electrical conductivity of 7353 Sm−1 at 30 vol. %. few-layer graphene loading.
