The integration of single-walled carbon nanotubes (SWCNTs) into many functional devices and applications requires the large-scale separation and dispersion of SWCNTs with known properties. A significant obstacle to the widespread use of SWCNTs in many applications is the formation of nanotubes with different electrical properties in nearly all synthetic techniques. Altering the interface around SWCNTs has been instrumental to the significant advances made in dispersing, integrating, and separating SWCNTs.

520 $a The integration of single-walled carbon nanotubes (SWCNTs) into many functional devices and applications requires the large-scale separation and dispersion of SWCNTs with known properties. A significant obstacle to the widespread use of SWCNTs in many applications is the formation of nanotubes with different electrical properties in nearly all synthetic techniques. Altering the interface around SWCNTs has been instrumental to the significant advances made in dispersing, integrating, and separating SWCNTs.
520 $a This study focuses on manipulation of the interface surrounding SWCNTs and characterization for both better separations and improved integration into applications. The separations studied are based on the aqueous two-phase (ATP) extraction method. A simple, one-step ATP extraction method is developed that achieves high purity fractions of the armchair metallic (5,5) SWCNT by altering the interaction of surfactants with the various species in the mixture. Meanwhile the interface surrounding the SWCNTs can be altered with polymers to impart new functionality. The biodegradable poly (butyl cyanoacrylate) (PBCA) is formed around the SWCNT surface through an in situ polymerization process. The chromophoric polymer tetraphenylporphyrin (TPP) was coated onto SWCNT surface for energy transfer purpose.
520 $a Characterization of the interfacial structure is important to developing better separations and applications. A combination of optical spectroscopy, proton nuclear magnetic resonance (NMR), and pulsed field gradient NMR (PFG NMR) techniques are used to monitor the interaction of sodium dodecyl sulfate (SDS) with SWCNTs at different surfactant concentrations. Distinct transitions in the NMR chemical shift are observed as the concentration of SDS is altered. These transitions are correlated to the critical micelle concentration (CMC) and are shown to be dependent on the amount of SWCNT suspended in the solution. At some ratios of surfactant to SWCNT, the observed CMC is even lower than the CMC for pure SDS, suggesting that the nanotube accelerates the aggregation of SDS. The results also indicate that there is a small fraction of SDS that remains tightly bound to the nanotube at nearly all concentrations.
