Abstract: Graphite nanosheets (nano-Gs) were prepared via sonication, of which teh particle size was about 10μm and average thickness was about 100nm, then using palladi μm-free stannous chlorid free electroless plating to plate Cu on the surface of nano-Gs. The PVC/Cu plating nano-Gs and PVC/CB/Cu plating nano-Gs composites were prepared by way of melt blending. The volμme resistivity of the PVC/Cu plating nano-Gs composites get the lowest value of 104Ω·cm when the mass fraction of Cu plating nano-Gs reached the percolation threshold(12%), but the tensile strength and notched impact strength of the composites both decrease compared with the pure PVC; when the mass fraction of Cu plating nano-Gs and CB was 10% and 2% ,respectively, the volμme resistivity of the PVC/CB/Cu plating nano-Gs composites get the lowest value of 103Ω·cm, an order of magnitude lower than PVC/Cu plating nano-Gs, and the tensile strength and notched impact strength of the composites both increased a lot compared with the neat PVC.
