Abstract

We present a route to synthesize polyacetylene filled multi-walled carbon nanotubes (MCNT) by in situ polymerization. We use supercritical carbon dioxide to fill the nanotubes with toluene and then add the Ziegler-Natta catalyst. In order to assure controlled polymerization inside the nanotube, the catalyst outside is removed before the reaction. The resulting polyacetylene filled nanotubes are characterized by 1 H NMR and scanning electron microscope.
