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。
This paper reviewed the recent progresses on the interface control in carbon nanotubes reinforced aluminum ma-trix composites ( CNT/Al) , including surface modification of CNTs, alloying of Al matrix, and the optimization and control of the fabrication technologies. The present research still has certain limitations, for example, lack of design and control of coating size and distribution, inefficiency of CNTs reinforcement effect. In order to fulfill the application and performance re-quirements of CNT/Al composites, special approaches need to be developed to realize the nano-level surface modification of CNTs, such as local decoration of CNTs surface, and optimization design of composite configuration. The size and distribution of nanoparticles should be finely and effectively controlled to obtain an ideal CNT/Al interface and improve reinforcement efficiency of CNTs.
