Macroscopic Ensembles of Aligned Carbon Nanotubes in Bubble Imprints Studied by Polarized Raman Microscopy
Figure 4
(a) Schematic of a bubble imprint representing measurement areas with polarized Raman microscopy. is defined as an angle between the laser polarization and -axis. Polarization angular dependence taken from (b) the top edge of the bubble membrane, (c) the right edge of the bubble membrane, (d) the center of the membrane, and (e) in the coffee ring. is defined as the nematic order parameters. (f) Illustration showing the orientation of SWCNTs in a bubble imprint.
