摘要：

We report a study on Dielectrophoresis Field Flow Fractionation of Single-Wall Carbon Nanotubes (SWNTs). SWNTs, individually suspended in 1% SDBS solution, were separated by type when they passed a dielectrophoresis field flow fractionation device where 1 MHz AC voltage was supplied and the field strength was well below 1 V per μm. Furthermore, we uniquely observed enrichment of semiconductive SWNTs based on their band gap. In addition to Raman spectrum, UV-vis absorption and NIR fluorescence spectra were used for solution samples for characterization. Copyright © 2006 American Chemical Society.
