Abstract
Supercritical carbon dioxide impregnation is used to prepare carbon nanotubes filled with pyrrole and
N-vinyl carbazole. After the impregnation, the monomers were polymerized inside the nanotubes. The samples are characterized by HRTEM and
1H NMR.
Supercritical carbon dioxide is an universal tool to impregnate carbon nanotubes with a wide range of organic molecules. In this Letter, we present our results of carbon nanotubes filled with the photo-conducting polymer poly(
N-vinyl carbazole) and the conducting polymer polypyrrole which were prepared by polymerizing the monomers inside the nanotubes. The endohedral nanotubes were characterized by HRTEM and
1H NMR which confirmed that the encapsulated material was indeed the conducting polymer.
