| 碳纳米管与铝基体的结合，可以获得导电和导热性良好及综合力学性能优异的复合材料，有望成为新一代轻质高强、结构功能一体化的复合材料。在制备碳纳米管增强铝基复合材料过程中，碳纳米管的团聚将降低界面结合，诱发缺陷产生，导致性能大幅下降，因此，调控优化碳纳米管的分散状态、含量成为获取良好界面结合，获得高性能碳纳米管增强铝基复合材料的关键。基于此，综述了国内外均匀分散碳纳米管的方法，通过物理作用、化学作用和物理化学共同作用的方式进行分类，并详细介绍了高能球磨、摩擦搅拌、化学气相沉积、湿法球磨等主要的碳纳米管在铝基体中的分散方法。分析了不同分散方法的特点及其分散效果，最后总结了分散过程中存在的分散效果、缺陷的平衡、大长径比、高含量碳纳米管分散及分散评价方法等关键问题，并展望了未来在铝及其合金基体中碳纳米管分散方法的发展方向。 |

| The combination of carbon nanotubes (CNTs) and aluminum matrix can produce a composite material with high electrical conductivity, thermal conductivity and excellent comprehensive mechanical properties, which is expected to become a new generation of lightweight and high-strength materials with structures and functions integrated. However, in the process of fabricating carbon nanotube reinforced aluminium matrix composites, the agglomeration of carbon nanotubes will reduce interface bonding, induce defects and cause an obvious drop of performance. Therefore, adjusting and optimizing the dispersion condition and content of carbon nanotubes has become the key in obtaining good interfacial bonding and high-performance carbon nanotube reinforced aluminium matrix composites. Therefore, the dispersing methods used for CNTs even dispersion at domestic and abroad are reviewed, and the CNTs dispersion methods have been classified based on physical, chemical, and physical-chemical interactions. Methods such as high energy ball milling, friction stirring, chemical vapor deposition and wet ball milling, and other methods have been introduced in detail. Meanwhile this paper analyzed the characteristics of different dispersion methods and their dispersion effects, and then summarizes the key problems in CNTs dispersion such as the balance between dispersion effect and CNTs defects, large aspect ratio and high content CNTs dispersion, the evaluation of CNTs dispersion effects, and closes by looking ahead to the development direction of CNTs dispersion methods in aluminum and aluminum alloy matrix. |
