Raman spectroscopy of polymer–carbon nanotube composites
H.D. Wagner, Weizmann Institute of Science, Israel
Abstract:
Over the past 30 years Raman spectroscopy has transformed the field of composite micromechanics and is being successfully applied to the field of nanotube-reinforced polymers. Under the effects of stress, careful study of the Raman spectrum of carbon nanotubes provides a unique insight into various physical phenomena in nanocomposites. This chapter demonstrates the power of the Raman signature of carbon nanotubes as a detector of bulk matrix defects, the occurrence of polymer phase transitions, and the nanotubes’ own orientation change with respect to applied stress, stress profiles from Raman-insensitive fibers, and ...
