ABSTRACT The nanostructured polyaniline (PANI) thin film has been prepared by using pulsed plasma
polymerization technique. The effects of substrate position, pressure and number of plasma
pulses on the film growth rate were monitored and established an ideal condition. The
characterization of prepared PANI thin film was performed with the ultraviolet-visible
spectroscopy (UV-Vis), Fourier transform infrared spectroscopy (FTIR) and scanning electron
microscope (SEM) studies. The surface of the thin film possessed three dimensional networks of
the PANI belts as cauliflower like morphology with a diameter of 35-97 nm. The NO2 gas sensing behavior was studied by measuring change in electrical conductivity with respect to
concentration and time. All the findings have been discussed and results would be appreciably
devoted in the area of sensor technology.
