Highly anisotropic polyolefin elastomer (POE)/natural graphite (NG) composites with high through-plane thermal conductivity and excellent mechanical properties, in which NG sheet perfectly aligns along one direction, are prepared by two-roll milling, hot compression, and mechanical cutting. The through-plane thermal conductivity coefficient of POE/NG composites is markedly improved to be 13.27 W m(-1) K-1 at an NG loading of 49.30 vol%. When the composite is used as a thermal management material, it shows excellent heat dissipating capability in the through-plane direction, which is very important for thermal management in electronic applications. This effective method is highly probable to be widely used for the facile fabrication of polymer-based thermal management materials.
