Self-Assembly of Pluronic Block Copolymers in Aqueous Dispersions of Single-Wall Carbon Nanotubes as Observed by Spin Probe EPR

AbstractWe describe the realization of high quality self-assembled single wall carbon nanotube field effect transistors (CNTFET). A method using self-assembled monolayers (SAMs) is used to obtain high yield selective deposition placement of single wall carbon nanotubes (SWNTs) on predefined regions of a substrate. This is achieved with individual or small bundles of SWNTs and with high densities suitable for fabrication of integrated devices. We show that such positioned SWNTs can be electrically contacted to realize high performance transistors, which very well compare with state-of-the-art CNTFETs. We therefore validate the self-assembly approach to reliably fabricate efficient carbon nanotube based devices.

The Individual

AbstractThe tendency of single wall carbon nanotubes to organize into crystalline ropes and the aggregation of the ropes into tangled networks act as an obstacle for most applications, and diminishes the special properties of the individual tubes. We describe a procedure for dispersing as-produced nanotube powder in aqueous solutions of Gum Arabic. Dispersion results in spontaneous exfoliation of nanotubes ropes into individual tubes, as demonstrated via x-ray scattering and electron microscopy.
