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 High Resolution Transmission Electron Microscopy (HRTEM) is an imaging mode of the transmission electron microscope (TEM) that allows the imaging of the crystallographic structure of a sample at an atomic scale. (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 In electron energy loss spectroscopy (EELS) a material is exposed to a beam of electrons with a known, narrow range of kinetic energies. Some of the electrons will undergo inelastic scattering, which means that they lose energy and have their paths slightly and randomly deflected.
