Highly conducting electrospun polyaniline-polyethylene oxide nanofibrous membranes filled with single-walled carbon nanotubes

Highly conducting nanofibrous composite of well-oriented single-walled carbon nanotubes (SWNTs) in polyaniline (PANI) and polyethylene oxide (PEO) have been fabricated using electrospinning. The room temperature electrical conductivity show nearly four order enhancement with highest (11.9 wt%) loading of SWNT in the PANI–PEO blend. The temperature dependent conductivities are measured in the range of 30–300 K and the results are analyzed by the fluctuation assisted tunneling model.
