NOVELTY - An aligned graphene sheets-polymer composite comprises: a polymer matrix; and aligned graphene sheets including graphene filament bundles disposed in the polymer matrix, and the graphene filament bundles are substantially parallel to each other. USE - As aligned graphene sheets-polymer composite (claimed), which is used as EMI shielding materials, thermal conductive graphite flakes, thermal interface materials, anisotropic electrical/thermal conductive materials or impact absorption materials. ADVANTAGE - The aligned graphene sheet-polymer composite exhibits an anisotropic behavior i.e. the composite has an anisotropy index of 1.30-2. Compared with the blended graphene sheets-polymer composite, the thermal conductivity of the aligned graphene sheet-polymer composite is equal to or more than three times of that of the blended graphene sheet-polymer composite. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacturing the aligned graphene sheets-polymer composite involving: dispersing the graphene sheets in a polymer fluid to form a mixture; applying a field in an acting direction to the mixture for the alignment of the graphene sheets to form the graphene filament bundles substantially parallel to each other in the polymer fluid, and solidifying the mixture to form the aligned graphene sheets-polymer composite, where the aligned graphene sheet-polymer composite has an anisotropy index of 1-2, which is the ratio of the thermal conductivity in a direction parallel to the field direction to the thermal conductivity in a direction vertical to the acting direction of the field.
