Electrical conductivity studies of zinc oxide, nickel doped zinc OxidePoly(O-Toluidine)nanocomposite using chemical oxidative polymerization

Abstract

NANOCOMPOSITE semiconductor material comprising Zinc oxide (ZnO), Nickel doped Zinc oxide and Poly(o-toluidine) polymeric composites were synthesized in two stage synthesis process. Solgel technique is adopted in the material synthesis of semiconductor particles of ZnO and Ni/ZnO (NZO), as well a proven technique of chemical oxidation of o-toluidine is attempted to prepare the semiconductor polymeric composites (ZPOT, NZPOT) and pure POT. The synthesized polymeric composites were characterized by (UV-Visible, XRD, SEM, FT-IR and TGA) spectroscopic studies. The addition of semiconductor material into the o-toluidine polymer resulted in a crystalline shape was confirmed from SEM image. Incorporation of metal oxide into polymeric composites showed a significant difference in the conductivity properties which were observed from DC conductivity studies.
