Controllable Expansion of Single-Walled Carbon Nanotube Dispersions Using Density Gradient Ultracentrifugation

  title={Controllable Expansion of Single-Walled Carbon Nanotube Dispersions Using Density Gradient Ultracentrifugation},
  author={Pei Zhao and Erik Einarsson and Rong Xiang and Yoichi Murakami and Shigeo Maruyama},
We present a protocol to selectively isolate single-walled carbon nanotubes (SWNTs) with different chiralities in a full-colored " rainbow " expansion using density gradient ultracentrifugation (DGU). Starting with SWNTs synthesized by the alcohol catalytic chemical vapor deposition (ACCVD) method, we used sodium deoxycholate (DOC) and sodium dodecyl sulfate (SDS) as co-surfactant encapsulating agents to form a DOC-restricted SDS wrapping morphology around the SWNTs. This enhances the density… CONTINUE READING
