摘要:

從碳納米管表面改性、金屬基體合金化和復合工藝優化三個方面綜述了碳納米管增強鋁基復合材料界面設計與調控的研究新進展，并對未來可能的發展新趨勢進行了展望。現有的界面設計研究尚存在一定的局限性，如碳納米管表面改性引入金屬或氧化物連續鍍膜將碳納米管與基體隔離，缺乏對鍍膜尺寸和分布的設計調控，未能有效發揮碳納米管自身的復合強化作用，未來需要針對復合材料的具體應用和性能需求，更有針對性地設計碳納米管的表面狀態或復合界面的結合程度，如：碳納米管表面缺陷修飾、復合材料構型優化設計等，并對表面修飾產物的尺寸和分布進行精細有效的調控，以獲得更為理想的界面狀態，充分發揮納米碳的增強效率。

Abstract:

This paper reviewed the recent progresses on the interface control in carbon nanotubes reinforced aluminum matrix 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 requirements of CNT/Al composites, special approaches need to be developed to realize the nano�瞝evel 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.
