Abstract

We report that dispersions and functionalizations of single-walled carbon nanotubes (SWNTs) with different dispersing methods and dispersing agents result in SWNTs with different electronic structures and surface chemistries. By In-situ polymerizing conducting polymer (here, polyaniline boronic acid (PABA)) in the presence of these SWNTs, we obtained composites with different chemical structures of PABA, different arrangement and distribution of the SWNTs, and dramatically different conductive properties. We also found the polymerization rates are very different depending on the electronic fingerprint and surface chemistry of the carbon nanotubes. We applied a series of techniques to characterize the produced composites and studying the electronic and molecular interactions in the composites to understand these remarkable effects.
