Study and Characterization of Nanostructure Plasma Polymerized Aniline Thin Films

Abstract

In this work, we have to prepared plasma polymerized aniline thin films. Plasma polymerization is a process of synthesis, in which crystal are changed in nanostructures. We have to monitor the growth rate of thin films with help of pulses and established an ideal condition. The characterization of 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. In PANI prepared through chemical route, however no aniline seems to exist. The PANI films prepared by plasma polymerization are less crystalline compared by chemical route. PANI films prepared by plasma technique are however totally free from reagent chemicals. The sufficient sensitivity could be obtained for plasma prepared PANI sensors; there may be no need to go through cumbersome chemical route.
