EFFECT OF SOLVENT AND DISPERSANT ON THE BUNDLE DISSOCIATION OF SINGLE-WALLED CARBON NANOTUBES

Abstract

Single-wall carbon nanotubes (SWNT) 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. In this work we present the results we obtained with 2,5-dioctyloxy-1,4-distyrylbenzene (pDSB), a short-chain analogues of the well known PPV. We found a strong dependence of the concentration at which individual SWNTs become stable with the nature of the solvent.
