Raman spectral shifts of single-wall carbon nanotubes embedded in polymer s
ystems were used to measure transitions in polymers. Glass-transition tempe
ratures and secondary transitions were observed, and Raman spectroscopic da
ta were compared with dynamic mechanical tests for a thermosetting and a th
ermoplastic polymer. The data confirm that the Raman spectral response of c
arbon nanotubes embedded in polymers is sensitive to polymer transitions. (
