Abstract
A method for fabricating an aligned graphene sheet-polymer composite is provided, which includes the steps below. A mixture is prepared with the dispersed graphene sheets in the polymer fluid. The graphene filament bundles substantially paralleled to each other are formed by a sequence of aligned graphene sheets in the polymer fluids when a field was applied. Finally, the mixture is solidified. An anisotropic index in a range of 1.00 to 2.00 is obtained in an aligned graphene sheet-polymer composite by calculating the ratio of the coefficient of thermal conductivity in a parallel direction and the one in perpendicular direction. The aligned graphene sheet-polymer composite is also provided.
