SCA-CNTs are nanostructured materials composed of single- or multi-layered graphene sheets rolled into tubular structures. Their key features include ultrasmall dimensions, large specific surface area, and high surface reactivity, resulting from their nanoscale morphology. The diameters of SCA-CNTs typically range from several nanometers to tens of nanometers, while their lengths can reach the micrometer scale. This distinctive microstructure endows SCA-CNTs with卓越的 mechanical properties, excellent electrical conductivity, and high thermal conductivity.

The preparation of SCA-CNTs primarily involves techniques such as chemical vapor deposition (CVD), liquid-phase exfoliation, and template synthesis. Among these, CVD is the most widely used method. By controlling growth parameters like temperature, pressure, and gas composition, uniform SCA-CNT arrays can be grown on substrates. This approach allows precise tuning of the nanotubes’ length, diameter, and spacing, offering flexibility for subsequent applications.
