Figure 5.9 SEM images of (a) fractured and (b) polished/ion-milled Al2O3/3 vol% MWNT nanocomposite. White dots in (b) are MWNTs. The circles and arrows indicate CNTs at the grain boundaries and within the grains, respectively.

Reproduced with permission from [44]. Copyright Ó (2003) Nature Publishing Group. Murkerjee and coworkers further investigated the effect of SPS temperatures on the microstructure and mechanical properties of the Al2O3/10 vol% SWNT nanocomposite. The nanocomposite specimens were sintered at 1150, 1350 and 1550 C for 3 min [69, 70]. Figure 5.11 shows the Raman spectra of the Al2O3/10 vol% SWNT nanocomposite sintered at 1150, 1350 and 1550 C for 3 min. The Raman spectrum of pure SWNT is also shown for the purpose of comparison. For SWNT, the peak at 1350 cm 1 corresponds to the D-band associated with the presence of disorder or small sp 2 carbon crystallite. The peak at 1595 cm 1 is assigned to the G-band resulting from the vibration mode (C C stretching) of sp 2 -bonded carbon atoms. A shoulder at 1560–1575 cm 1 is due to the overlapping of electrons within graphene layers upon rolling the layers into nanotubes. From Figure 5.11, the Figure 5.11 Pulsed laser Raman spectra of Al 2O 3/10 vol% SWNT nanocomposite spark plasma sintered at 1150, 1350 and 1550 C for 3 min. The Raman spectrum of pristine SWNT is also shown for comparison. Reproduced with permission from [70]. Copyright Ó (2007) Elsevier.
