Raman Mapping of Single-Walled Carbon Nanotube Distribution on Phase Separated Polystyrene and Polymethylmethacrylate

In this application note, phase separated polystyrene and polymethylmethacrylate polymers were vapor deposited onto silicon. To ensure that these materials were indeed phase separated, dispersive Raman mapping was used to show the distribution of the polymers. The size of the structures varied from 10-50 microns in width. Single-walled carbon nanotubes were then vacuum-deposited onto the surface.
