As classical 1D nanoscale structures, carbon nanotubes (CNTs) possess remarkable mechanical, electrical, thermal, and optical properties. In the past several years, considerable attention has been paid to the use of CNTs as building blocks for novel high-performance materials. In this way, the production of macroscopic architectures based on assembled CNTs with controlled orientation and configurations is an important step towards their application. So far, various forms of macroscale CNT assemblies have been produced, such as 1D CNT fibers, 2D CNT films/sheets, and 3D aligned CNT arrays or foams. These macroarchitectures, depending on the manner in which they are assembled, display a variety of fascinating features that cannot be achieved using conventional materials. This review provides an overview of various macroscopic CNT assemblies, with a focus on their preparation and mechanical properties as well as their potential applications in practical fields.
作为经典的一维纳米结构,碳纳米管(CNTs)具有显著的力学、电学、热学和光学性能。在过去的几年中,人们对将 CNT 用作新型高性能材料的构建块给予了极大的关注。通过这种方式,基于组装 CNT 并控制其取向和结构的宏观结构的生产是实现其应用的重要步骤。到目前为止,已经制备了各种形式的宏观 CNT 组装体,例如一维 CNT 纤维、二维 CNT 薄膜/片材和三维取向 CNT 阵列或泡沫。这些宏观结构根据组装方式的不同,表现出许多使用传统材料无法实现的迷人特性。本综述重点介绍了各种宏观 CNT 组装体,包括它们的制备方法、力学性能以及在实际领域中的潜在应用。
