Carbon Nanotube 3D Architectures: from Micro- to Macro-scales

Carbon nanotubes (CNTs) are currently on the cutting edge of nanotechnology and material science and their applications in our daily life have gradually increased in the past years in various fields, such as life science, energy storage, biomedical, and environmental applications. In the past decades, great achievements have been made in the development of long fibres or 2D CNT films with promising properties for commercial applications. However, CNT 3D architectures with highly porous and hierarchical structures and specific shapes and volumes are promising for a broader range of fields. This review article summarizes the most common fabrication methods used for the preparation of CNT 3D architectures and their influence on the final material properties.
