In order to meet the requirement of thermal performance with the rapid development of high-performance electronic devices, constructing a three-dimensional thermal transport skeleton is an effective method for enhancing the thermal conductivity of polymer composites. In this work, a three-dimensional porous diamond framework was prepared by depositing nano-crystalline diamond on alumina foam which was impregnated with epoxy to obtain a nano-crystalline diamond@alumina foam/epoxy composite. The epoxy composite with nano-crystalline diamond@alumina foam demonstrated a thermal conductivity of 2.21 W m K, which was increased by 1063% in comparison with pure epoxy. The thermal conductivity of the epoxy composite measured under various conditions and heat transport applications demonstrates that it possesses excellent thermal transportation and stability properties. This work provides a new idea to significantly enhance the thermal transportation properties of epoxy composites in the application of advanced packaging materials.
随着高性能电子设备的快速发展，为满足热性能要求，构建三维热传输骨架是提高聚合物复合材料热导率的有效方法。在本工作中，通过在浸渍有环氧树脂的泡沫氧化铝上沉积纳米晶金刚石制备了三维多孔金刚石骨架，从而获得纳米晶金刚石@泡沫氧化铝/环氧树脂复合材料。含有纳米晶金刚石@泡沫氧化铝的环氧树脂复合材料的热导率为2.21W/(m·K)，与纯环氧树脂相比提高了1063%。在各种条件下测量的环氧树脂复合材料的热导率以及热传输应用表明，它具有优异的热传输和稳定性。这项工作为在先进包装材料应用中显著提高环氧树脂复合材料的热传输性能提供了新思路。
