通过两辊铣削、热压缩和机械切割制备了高度各向异性聚烯烃弹性体（POE）/天然石墨（NG）复合材料，该复合材料具有高平面导热率和优异的机械性能，其中NG片材沿一个方向完美排列。当NG负载量为49.30 vol%时，POE/NG复合材料的贯通面导热系数显着提高至13.27 W m(-1) K-1。当该复合材料用作热管理材料时，它在平面方向上表现出优异的散热能力，这对于电子应用中的热管理非常重要。这种有效的方法很可能广泛用于聚合物基热管理材料的简便制造。
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.
