Abstract:Raman spectra of highly oriented pyrolitic graphite, multilayer graphene and multiwall carbon nanotubes are carried out at different laser powers and different excitation energies. The effects of the laser heating and the double resonance Raman scattering are investigated as a prerequisite for a correct interpretation of the Raman spectra of carbon materials-based composites. The Raman spectra of multilayer graphene and multiwall carbon nanotubes embedded in a silicone matrix are also analyzed in an attempt to get some insights into the polymer–filler interface.
