Electrical conductivity and Raman imaging of double wall carbon nanotubes in a polymer matrix [PDF]

, 2011
Raman spectroscopy is used to access the dispersion state of DWNTs in a PEEK polymer matrix. The interaction of the outer tube with the matrix can be determined from the line shape of the Raman G band.
