[Show abstract][Hide abstract] 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.

[Show abstract][Hide abstract] 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.
[Show abstract][Hide abstract] 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.
