Debundling of single-walled nanotubes by dilution: Observation of large populations of individual nanotubes in amide solvent dispersions

Article Abstract:

Atomic force microscopy (AFM), ultraviolet (UV)-vis-near infrared (NIR) absorption, NIR photoluminescence and Raman spectroscopy are used to demonstrate that single-walled nanotubes can be debundled simply by reducing the nanotube concentration in N-methyl-2-pyrrolidone (NMP) dispersions. The findings reveal that the average bundle diameter decreases with decreasing concentration of 8 x [10.sup.-3] mg/mL.

Binding kinetics and SWNT bundle dissociation in low concentration polymer-nanotube dispersions

Article Abstract:

A new spectroscopic method is described in this work, to measure the ratio of free polymer to nanotube-bound polymer in SWNT/polymer solutions. This ratio is highly nonlinear and can be described by a model based on polymer-nanotube adsorption/desorption kinetics.
