    ABSTRACT: The present investigation is primarily focused on the study of effect of nanosized clay and TiO2 on the structure and thermal properties of electrically conducting poly (aniline-co-o-toluidine)/nanocomposite system. These nanocomposites are synthesized by the in situ oxidative polymerization method with peroxy disulphate as a lone chemical initiator, HCl as an external dopant and clay and TiO2 as a host material. The nanocomposites are characterized by analytical tools like Fourier transform infrared, Keithley instrument, thermal gravimetric analysis, and high resolution transmission electron microscopy.

    ABSTRACT: This paper explains the synthesis and characterizations of Poly(aniline) (PANI)/Sb2O3 nano composite by in-situ polymerization method. It was indicated that Sb2O3 itself could catalyze the oxidative polymerization of aniline through its active surface effect. This could be due to the intercalation of PANI chains into the basal spacing of Sb2O3. TGA counseled the thermal stability of PANI. Through FTIR study, the structure of PANI was confirmed. Comparison of polymerized aniline composite with two different initiators was done. HRTEM confirmed the nano size of Sb2O3. The intercalating nature of PANI chains into the basal spacing of Sb2O3 was also tested.

    ABSTRACT: Chemical oxidative polymerization of aniline (ANI) and o/m-toluidine (OT or MT) and their nano composites at different experimental conditions were performed using peroxydisulfate (PDS) as a lone chemical initiator and V2O5 as a host material in an aqueous HCl medium at 45 °C under nitrogen atmosphere. The nano composites were synthesized under different experimental conditions and were characterized by Fourier transform infra red (FTIR) spectroscopy, conductivity measurements, high resolution transmission electron microscopy (HRTEM) and thermogravimetric analysis (TGA) like analytical tools. The effect of methyl substituent in the phenyl ring of ANI derivatives on the structure and property relationship of copolymer was studied.

    ABSTRACT: This study is focused on the preparation and characterisation of conducting poly(aniline-co- o / m -toluidine)/Sb<sub>2</sub>O<sub>3</sub> nanocomposites. These nanocomposites were synthesised by the oxidative chemical polymerisation with peroxydisulphate as an oxidant in aqueous hydrochloric acid (HCl) medium and Sb<sub>2</sub>O<sub>3</sub> as a nanomaterial under different experimental conditions. The nanocomposites were characterised by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis, high-resolution transmission electron microscopy and conductivity measurements. FTIR-based kinetics was proposed based on the relative intensities of FTIR peaks.

    ABSTRACT: Aniline was polymerized under different experimental conditions like variation in time, temperature, monomer and concentration of initiators. Relative intensity of the benzenoid and quinonoid forms were estimated and correlated with poly(aniline) (PANI) structure. TGA counseled the thermal stability of poly(aniline). Through FTIR study, the structure of poly(aniline) was recognized. Comparison of polymerized aniline with two different initiators was done.
