In this work Raman spectroscopy was used for extensive characterization of multiwall carbon nanotube (MWNTs) and of MWCNTs/rubber composites. We have measured the Raman spectra of bundled and dispersed multiwall carbon nanotubes. All the Raman bands of the carbon nanotubes are seen to shift to higher wavenumbers upon debundling on account of less intertube interactions. Effects of laser irradiation were also investigated. Strong effects are observed by changing the wavelength of the laser excitation. On the other hand, at a given excitation wavelength, changes on the Raman bands are observed by changing the laser power density due to sample heating during the measurement procedure.

• Raman Spectra of Carbon-Based Materials (from Graphite to Carbon Black) and of Some Silicone Composites (2015, background): “They are easily observed in all samples (excepted of course the D band in HOPG), and furthermore, their positions determined after spectral deconvolution closely match those observed directly on the experimental spectra (excepted the 2D band in GO and CB samples).”
