Abstract
Polyaniline (PANI) and molybdenum disulphide (MoS
2
) were used to prepare nanocomposites
by in-situ oxidative polymerization of acidified aniline in presence of dispersed MoS
2 in the
reaction mixture. Electron Microscopy (SEM & TEM), Fourier Transform Infrared (FTIR)
spectroscopy, Ultraviolet-Visible (UV-Vis) spectroscopy, and X-ray diffraction (XRD) were used
to characterize these nanocomposites. SEM micrographs showed that PANI is present on the
layers of MoS
2
which were exfoliated during the preparation and the presence of MoS
2
is also
confirmed by XRD peaks. The nanocomposites were studied for their electrical conductivity
and stability of electrical conductivity in terms of d.c. electrical conductivity retention. Further,
the nanocomposites were also studied for their sensing behaviour towards alcohol, ketone,
aldehyde in ambient condition. These nanocomposites were found to be semiconducting, stable
upto 100°C and exhibited good sensitivity towards above mentioned group of volatile organic
compounds (VOCs).
