Through 30 years of research, researchers have gained a deep understanding of the synthesis, characteristics, and applications of carbon nanotubes (CNTs). However, up to now, there are still few industries using CNT as the leading material. The difficulty of CNTs to be applied in industry is the gap between the properties of CNT-based aggregates and those of a single carbon nanotube. Therefore, how to maintain the intrinsic properties of CNTs when they are assembled into aggregates is of great significance. Herein, we summarize and analyze the research status of CNT materials applied in different fields from proven techniques to potential industries, including energy storage, electronics, mechanical and other applications. For each application, the intrinsic properties of CNTs and the real performances of their aggregates are compared to figure out the key problems in CNT synthesis. Finally, we give an outlook for building a bridge for CNTs from nanoscale structure to macroscopic application, giving inspiration to researchers making efforts toward the real application of carbon nanotubes.
经过 30 年的研究，研究人员对碳纳米管（CNT）的合成、特性和应用有了深入的了解。然而，到目前为止，仍很少有行业将 CNT 作为主导材料。CNT 在工业中应用的困难在于基于 CNT 的聚集体的性质与单个碳纳米管的性质之间存在差距。因此，如何在组装成聚集体时保持 CNT 的固有特性具有重要意义。在此，我们从已证实的技术到潜在的产业，总结和分析了 CNT 材料在不同领域的应用研究现状，包括储能、电子、机械等应用。对于每种应用，我们比较了 CNT 的固有特性与其聚集体的实际性能，以找出 CNT 合成中的关键问题。最后，我们为 CNT 从纳米结构到宏观应用架起桥梁提供了展望，为努力实现碳纳米管实际应用的研究人员提供了启示。
