Synthesis, structural, morphological, optical and electrical conductivity properties of aluminium doped ZnO/POLY (o-TOLUIDINE) (Al-ZnO-POT) nanocomposites

Aluminium doped Zinc oxide (Al-ZnO) nanoparticles synthesized by chemical precipitation method. Chemical oxidative polymerization ofo-toluidine monomer for the synthesis of Poly (o-toluidine) (POT)polymer and its nanocomposites with Al-ZnO nanoparticles(Al-ZnO-POT)employing ammonium persulfate as an oxidizing agent in aqueous medium.Synthesized nanoparticles, polymer and nanocomposites were characterized with XRD studies, FTIR, SEM, EDAX, UV-Vis and PL analysis.The XRD pattern confirms an amorphous structurein Al -ZnO-POTnanocomposities.The FTIR pattern confirmsfunctional group and chemical bonding present in the synthesiszedsamples.SEM images confirm the nanorod shapeof nanoparticles. EDAX images confirm the elemental composition of the synthesized samples.The optical property of the particles wasanalysedby UV-Visible and PL Spectra.Incorporation of nanoparticles, polymer and nano composites showed a significant difference inelectrochemical conductivity properties were analysed by using four probe DC electrical conductivity instrument from room temperature 32°C to higher temperature 120°C.
