摘要:: 从高导热复合构型、高导热复合界面及新型高导热纳米碳增强体3个方面，综述了热管理用铜基和铝基功能复合材料的研究进展，并对高导热金属基复合材料的未来发展方向进行了预测与展望。在材料组分相同的情况下，基于金属基体与导热增强体之间复合构型和复合界面的差异，制备的金属基复合材料的导热与热膨胀性能会发生显著变化。此外，由于纳米增强体与基体在形貌、尺寸及表面化学性质等方面的不相容性，在新型高导热金属基纳米复合材料的研发过程中，更需要兼顾高导热复合构型与复合界面的优化设计。可以预言，采用碳纳米管、石墨烯纳米片等新型纳米碳增强体，设计与制备具有微/纳米跨尺度分级复合构型的金属基复合材料将成为未来的研究热点。

Abstract:: Progress of the metal matrix composites (MMCs) for thermal management applications was summarized with regard to high conductive architecture, interface and the novel carbon nanophases. There are great variations on thermal conduction and expansion for composites with the same composition but different architectures as well as interfaces. Due to the incompatibilities of the morphology, dimension and surface chemistry between metal powders and nanophases, additional attentions must be paid to optimize the architecture and interface in the R&D of such nanocomposites. It can be expected that a micro/nano hierarchical architecture in combination with carbon nanophases such as carbon nanotubes and graphene nanosheets will become the hotspot in the near future.
