Abstract:
In this presentation, we report that dispersion and functionalization of single-walled carbon nanotubes (SWNTs) with different dispersing methods and dispersing agents result different SWNTs with different electronic structures and surface chemistries. In-situ polymerization of the conducting polymer (here, also polyaniline boronic acid) in the presence of these varied SWNTs, we obtained composites with different chemical structures and chemical stabilities. We also found the polymerization rate is very different depending on the electronic fingerprint of the carbon nanotubes. We applied a series of techniques characterizing the produced composite and studying the electronic origins of these remarkable effects.
