Polypyrrole-carbon nanotube composite films synthesized through gas-phase polymerization

Polypyrrole-carbon nanotubes (CNTs) composite films, having high conductivity and uniformity, were directly synthesized by depositing polymerization in the gas-phase. The conductive polypyrrole was filled as a matrix material between the CNT networks by self-organization of the pyrrole monomer. Compared to the traditional composite technique and film-coating procedures, this process can be largely increased the carrier mobility for electrical conductivity because act to conducting bridge connecting PPy, increased the conductivity up to five times, and simultaneously improved the thermal stability. The characterization of the composite film was established by TEM. XRD, TGA, and IR/Raman spectroscopic analysis. (C) 2010 Elsevier B.V. All rights reserved.
