Synthesis and Structural Characterization of Polyaniline–Tin-Oxide Nanocomposite for Device Application

Abstract

In this research, polyaniline (PANI) and tin (iv) oxide (SnO₂) nanoparticles and polyaniline/SnO₂ nanocomposites were successfully synthesized by chemically oxidative polymerization of aniline in the presence of hydrochloric acid using ammonium persulfate as an oxidizing agent. The purpose of this study is to synthesize and investigate polyaniline/tin (iv) oxide nanocomposite for optoelectronics application. The synthesized nanocomposites were characterized to ascertain possible applications of the nanocomposites. The x- ray diffraction (XRD) analysis was carried out using x-ray diffraction machine. The results of the structural analysis showed that the formed polyaniline is a polymer, while SnO₂ showed tetragonal rutile phase. The average crystallite size of was obtained for SnO₂.  PANI/SnO₂ nanocomposites have structural pattern of tetragonal rutile phase and an average crystallite size range between  and were obtained.  The obtained results in this study revealed good results which are comparable with results obtained by other researchers in literature. These results obtained suggest the possibility of using the material in optoelectronics devices like LEDs, solar cells, transducers, and photodetectors.
