Structural and Optical Characterization of In_2O_3/PANI Nanocomposite Prepared by In-situ Polymerization

摘要

Polyaniline-indium oxide (In_2O_3/PANI) nanocomposite have been prepared by in-situ polymerization of aniline and as-synthesized In_2O_3 nanoparticles. X-ray diffraction (XRD), Transmission electron microscopy (TEM), Fourier transformation infrared (FTIR) and UV/Vis spectroscopy techniques are used to investigate the structural and optical properties of In_2O_3/PANI nanocomposite. TEM analysis shows In_2O_3 nanoparticles are embedded in PANI nanofibers. FTIR spectra show the good interactions between PANI nanofibers and In_2O_3 nanoparticles. The band gap and electronic transitions in In_2O_3/PANI nanocomposite is determined by using UV/Vis spectra.
