General description
Multi-walled carbon nanotubes are aligned in a direction. The CNTs are just connected with van der Waals forces, and no binder material is used. The sheet shows high anisotropic transport properties, including electrical conductivity and thermal conductivity.
CNT has a multi-walled structure. Crystal quality of CNT is examined by Raman scattering measurement. Intensity ratio of G-peak (1580 cm-1) and D-peak (1350 cm-1) represents quality of graphitization of carbon materials. G/D of CNT is ~3, showing high crystal quality. The high crystallinity is supported by transmission electron microscopy.
