摘要：

In order to solve problems of low alignment accuracy and poor performance enhancement of carbon nanotubes, existing control methods for directional alignment of carbon nanotubes are reviewed, and application progresses of aligned carbon nanotubes in the fields of electricity, mechanics and thermology are summerized. Mechanism for improving matrix material properties of carbon nanotubes is analyzed based on the comprehensive review. The role of carbon nanotube fiber bridging in matrix toughening is clarified, which provides solutions to problems like poor dispersing performance and low interfacial combination strength of carbon nanotube. It is found that the formation of carbon nanotube particle chain promotes performance extension of carbon nanotube properties in axial direction. Compared with applications in mechanical and thermal fields, higher alignment accuracies are required in electricity for modified electrical properties of carbon nanotubes. Through an objective description and comprehensive analysis on the existing research results, it is concluded that traditional control methods cannot be applied in precise applications of carbon nanotubes. Three topics of carbon nanotube research should be focused, i. e., precise control of directional alignment, combination of three-phase interface, and mass production technology. These results show the directions of future research of carbon nanotubes. © 2022, Editorial Office of Journal of Xi'an Jiaotong University. All right reserved.
