摘要:

從高導(dǎo)熱復(fù)合構(gòu)型、高導(dǎo)熱復(fù)合界面及新型高導(dǎo)熱納米碳增強(qiáng)體3個(gè)方面，綜述了熱管理用銅基和鋁基功能復(fù)合材料的研究進(jìn)展，并對(duì)高導(dǎo)熱金屬基復(fù)合材料的未來(lái)發(fā)展方向進(jìn)行了預(yù)測(cè)與展望。在材料組分相同的情況下，基于金屬基體與導(dǎo)熱增強(qiáng)體之間復(fù)合構(gòu)型和復(fù)合界面的差異，制備的金屬基復(fù)合材料的導(dǎo)熱與熱膨脹性能會(huì)發(fā)生顯著變化。此外，由于納米增強(qiáng)體與基體在形貌、尺寸及表面化學(xué)性質(zhì)等方面的不相容性，在新型高導(dǎo)熱金屬基納米復(fù)合材料的研發(fā)過(guò)程中，更需要兼顧高導(dǎo)熱復(fù)合構(gòu)型與復(fù)合界面的優(yōu)化設(shè)計(jì)�？梢灶A(yù)言，采用碳納米管、石墨烯納米片等新型納米碳增強(qiáng)體，設(shè)計(jì)與制備具有微/納米跨尺度分級(jí)復(fù)合構(gòu)型的金屬基復(fù)合材料將成為未來(lái)的研究熱點(diǎn)。��

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.
