从碳纳米管表面改性、金属基体合金化和复合工艺优化三个方面综述了碳纳米管增强铝基复合材料界面设计与调控的研究新进展,并对未来可能的发展新趋势进行了展望。现有的界面设计研究尚存在一定的局限性,如碳纳米管表面改性引入金属或氧化物连续镀膜将碳纳米管与基体隔离,缺乏对镀膜尺寸和分布的设计调控,未能有效发挥碳纳米管自身的复合强化作用,未来需要针对复合材料的具体应用和性能需求,更有针对性地设计碳纳米管的表面状态或复合界面的结合程度,如:碳纳米管表面缺陷修饰、复合材料构型优化设计等,并对表面修饰产物的尺寸和分布进行精细有效的调控,以获得更为理想的界面状态,充分发挥纳米碳的增强效率。
The recent progress in the design and control of the interface of carbon nanotubes reinforced aluminum matrix composites was reviewed in three aspects, including the surface modification of carbon nanotubes, the alloying of the metal matrix and the optimization of the composite process. Finally, some possible new trends in the future were prospected. Existing interface design and research there are still some limitations, such as the introduction of surface modification of carbon nanotubes or metal oxide continuous coating of carbon nanotubes and the substrate isolation, the lack of design and control of the coating size and distribution of the failure to effectively play the role of carbon In the future, it is necessary to design the surface state of the carbon nanotube or the combination interface of the composite nanotubes more specifically according to the specific application and performance requirements of the composite material, such as the surface modification of the carbon nanotube, the composite material Configuration optimization design, and the size and distribution of surface modification products for fine and effective regulation, in order to obtain a more ideal interface state, give full play to the enhanced efficiency of nano-carbon.
