Characterization of functionalized single-walled carbon nanotubes at individual nanotube level. (South Carolina Academy of Sciences Abstracts).

Individual and thin bundles of aminopolymer-functionalized single-walled carbon nanotubes (SWNTs) were successfully imaged using high-resolution transmission electron microscopy (HR-TEM). The amorphous materials covering the nanotube surface of SWNTs were confirmed to be preimiarly nitrogen-containing polymer functionalities by corresponding electron energy loss spectroscopy (EELS) characterization before and after ex situ thermal defunctionalization of the sample of the same TEM specimen. In addition, the strategy of ex situ thermal defunctionalization was also applied to other functionalized SWNT samples to achieve efficient HR-TEM imaging.
