Preparation of Graphene-containing Composite Film and Its Thermal Conductivity

摘要：

　　A smooth and flexible carbon film was prepared via liquid exfoliation method followed by liquid evaporation using the natural flake graphite as the starting material.The XRD and Raman results demonstrated that the obtained film is composed of chemically reduced graphene,graphene oxide and graphite.The thermal transport property of the as-obtained film was investigated by light flash measurements.It is found that the as-obtained graphene-containing composite film has a high in-plane thermal diffusivity (2157 m2/s),and the corresponding thermal conductivity (754 W/m K) is higher than the other metal and normal graphite materials,which is very promising for applications requiring 2D heat conduction.
