Probing structure and strain transfer in dry-spun carbon nanotube fibers by depth-profiled Raman spectroscopy

Probing structure and strain transfer in dry-spun carbon nanotube fibers by depth-profiled Raman spectroscopy

The structural properties of dry-spun carbon nanotube (CNT) fibers were characterized by depth-profiled polarized Raman spectroscopy. Results showed that the twisting cannot be fully transferred through the whole fiber and the CNTs within fibers possess non-uniform alignments in radial direction. Ef...
