| The ability to stepwise assemble polymer/single walled carbon nanotube (SWCNT) films using donor-acceptor interaction will be presented. Our approach to the “bottom-up” formation of polymer/SWCNT composite films utilizes the affinity that basic nitrogen groups possess towards single walled carbon nanotubes. Using various nitrogen containing polymers, films were formed via the sequential adsorption of polymer followed by SWCNTs onto substrates. Atomic force and scanning electron microscopies demonstrated that the films were composed of single nanotubes and small bundles, that surface coverages were uniform, and that film growth was linearly related to the number of polymer/SWCNT adsorption cycles. We will also demonstrate the ability to use the as-assembled polymer/SWCNT films as “scaffolds” to form novel polymer/SWCNT/silica films via sol-gel processing. |
