dc.description.abstract | Single-wall carbon nanotubes (SWCNT) are severely restricted in their applications, as they exist in rope-like bundles.
Recently, J. Coleman et al. demonstrated a spectroscopic method to monitor bundle dissociation in low concentration
NT-polymer composites.1 The method relies on the measurement of the ratio of free-polymer to the nanotube-bound
polymer in the SWCNT-polymer solutions via luminescent spectroscopy. A theory has been developed to transform this
data into the bundle surface area, which is of course related to the bundle size. This method clearly shows that
individual, isolated SWCNT are stable in low concentration dispersions.
The main aim of this work is to better understanding of the physics behind polymer ? SWCNT interactions, the binding
scheme, and the magnitude of the polymer ? SWCNT binding energy. In an effort to broaden the understanding of the
physical processes governing the NT de-bundling a wide range of suitable polymers and short-chain molecules have
been examined. We found a strong dependence of the concentration at which individual NTs become stable with the
nature of the dispersant molecule | en |
