Description	Simple technology (i.e. one-step polymerization of anilinium sulfate in the presence of montmorillonite) have been used to prepare the polyaniline/montmorillonite (PANI/MMT) nanocomposite thin films. Present work is focused on the effect of MMT content on the thickness, morphology and electrical conductivity of PANI/MMT nanocomposite films. Increase of MMT content led to the increase of film thickness and surface roughness and decrease of conductivity from maximum value 356 S/m to minimum value 76 S/m, while for pure PANI films, prepared using the same polymerization procedure (from anilinium sulfate) the conductivity was 59 S/m. On the other hand the MMT content exhibited significant impact on the optical transparency of PANI/MMT nanocomposite films, which was limited to the range 450 - 650 nm in contrast with pure PANI films showing the nonzero transparency in the whole measured range of wavelength 300-800 nm. AFM images clearly proved the alignment of PANI chains in nanocomposite films in comparison with pure PANI films. SEM images revealed in details the significant difference in surface morphology for pure PANI films and PANI nanofilms covering the MMT particles.
