Polyaniline-CuO nanocomposite: Electrical, structural and sensor properties

Abstract This research paper presents the synthesis and characterization of polyaniline (PANI) and PANI/Copper oxide (PANI/CuO) nanocomposites. PANI was synthesized using chemical a route and PANI/CuO Nanocomposite was prepared using mechanical mixing method. The prepared samples were characterized for FTIR, XRD, SEM, Electrical conductivity using four probe method and methanol gas sensing properties. FTIR spectra confirm the presence of characteristics peaks of PANI. XRD spectrum indicates the presence of copper oxide nanoparticles in PANI and SEM micrographs indicate the distribution of copper oxide nanoparticles in PANI matrix. Electrical conductivity of PANI has been decreased in the presence of different weight percent of CuO. Gas sensing of the response of PANI-CuO was observed higher compared to pure PANI.
