Mass-spectrometric study of single-walled carbon nanotubes modified by aliphatic amines
The gas-phase derivatization procedure was employed for direct (i.e., without chemical activation of terminal carboxylic groups) amidization of oxidized single-walled carbon nanotubes (SWNTs) with simple aliphatic amines. The procedure includes treatment of SWNTs with amine vapors under reduced pres...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The gas-phase derivatization procedure was employed for direct (i.e., without chemical activation of terminal carboxylic groups) amidization of oxidized single-walled carbon nanotubes (SWNTs) with simple aliphatic amines. The procedure includes treatment of SWNTs with amine vapors under reduced pressure and temperature of 160-170ºC. Applicability of temperature-programmed desorption mass spectrometry for chemical characterization of the derivatized SWNTs was analyzed. Heating of the amine-treated SWNTs at temperature >200ºC causes cleavage of alkenes from the amine residues: nonene and pentene are formed in the case of nonylamine and dipentylamine, respectively.
