“…Thus, polymers demonstrate dual character and reveal properties of both semiconductors and metals. Low charge carrier mobility (10 -1 -10 -4 cm 2 •V -1 •s -1 for PANI (Harima et al, 2001) and their high concentration (3•10 20 spin•g -1 ) comparable with carrier concentration in metals provide evidence that there are mechanisms of localization of charge carriers in macroscopic samples.…”

“…Usually, the electrosynthetic film thickness is estimated by the charge amount of polymerization, the weight of film, optical absorbance of film or other indirect methods. 4,14,20,21 In this work, the thickness of the PANI film is directly measured by a shift of the focus plane of optical microscope (Olympus BH2-UMA). Before measurement, the shift scale of focus plane of this microscope was verified using a standard glass plate of 100 µm thickness.…”

The in-situ apparent mobility in polyaniline films was accurately measured in a wide doping region using a new four-band electrode. It was found the apparent mobility in polyaniline films rises with increasing the doping level or carrier density. The influence of film thickness on the conductivity and apparent mobility of charge carriers was also investigated. The relative higher conductivity observed in a thinner film under low and intermediate doping potentials is assigned to the higher inter-chain mobility related to the more ordered structure of the film. The mobility variations provide experimental evidence to confirm the inter-chain path for hopping transport of polarons and the intra-chain path for evolution of metallic conduction.

Thin, transparent, and self‐assembled films of neat polyaniline and polyaniline/carbon nanotube nanocomposites were deposited over glass substrates by interfacial polymerization. The effect of the carbon nanotubes on the structure and conformation of the polyaniline, and the type of interaction between the polymer and the nanotubes, have been studied by resonant Raman spectroscopy and UV–Vis and Raman spectroelectrochemistry. The results indicate clearly that the carbon nanotubes induce important changes in the electronic structure of the polymer, resulting in a more polaronic organization. Additionally, an effective interaction between the polymer and the nanotube, based on a polyaniline‐to‐nanotube charge transfer, is proposed in this work. Copyright © 2012 John Wiley & Sons, Ltd.
