Raman spectrum of the surface of a spin-casted purified (solid line) SWNT film and (dashed line) ASWNT film.
SEM micrographs of (a) the surface of the polymer nanotube films and (b) of nanotubes protrude from the edge of the polymer film.
Plot of room conductivity of a P3OT-SWNT composite with or without purification, as a function of the SWNTs content.
The temperature dependence of the (a) electrical conductivity and (b) the normalized conductivity of the composite with different concentrations of SWNTs above the percolation threshold. The conductivity of the SWNT mat is also shown.
Temperature dependence of the normalized conductivity of (a) SWNTs based on the VRH model and (b) P3OT-SWNT composites based on the FIT model.
Plot of and as a function of SWNT weight fraction .
and values derived from Fig. 5(a), using Eq. (3).
