dc.description.abstractA novel route to prepare polyaniline (PANI) using two oxidizing agents, ammonium peroxydisulfate (APS) and sodium hypochlorite (NaOCl) which represents a facile synthetic method for the synthesis of high conductive PANI nanofibers. NaOCl acts as a co-oxidant to speed up the polymerization rate and direct the growth of PANI into nanofibers. PANI was polymerized in the presence of copper(II) oxide (CuO) or calcium(II) oxide (CaO) using these two oxidizing agents. The effect of different metal oxide contents to the morphology, electrical conductivity and thermal stability of PANI was studied systematically in this work. The physical interaction between PANI and metal oxides were monitored by Fourier Transforms Infrared Spectroscopy (FTIR) and Ultraviolet-Visible Spectroscopy (UV-Vis). The results revealed that maximum interaction was found for the PANI-CuO nanocomposite with 0.010 g CuO and the PANI-CaO nanocomposite with 1.000 g CaO, respectively. From the Scanning Electron Microscopy (SEM) observation, the prepared nanocomposites were of nanofibers structure with diameter sized 60 - 100 nm and distribution of metal oxide nanoparticles (10 - 20 nm), showing that the use of APS and NaOCl hindered the growth of PANI into nanoparticles agglomeration due the nucleus effect of metal oxide. The structural PANI nanocomposites were further supported by Transmission Electron Microscopy (TEM). A significant increase in electrical conductivity has been observed upon the addition of metal oxide.en_US
