“…Dutta et al [14] measured same result for PANI/SnO 2 nanocomposites [15]. The vibration band around 1550-1650cm -1 [13] is due to the C-N stretching vibration of quinoid rings whereas the vibration band around 1439-1498 cm -1 [13] arises due to the C-N stretching vibration associated with the benzenoid ring.…”

“…3. The peaks at 616.7 cm −1 corressponds [13] to the anti-symmetric Sn-O-Sn mode. Strong peaks at 613 cm −1 in both the samples are due to the anti-symmetric Sn-O-Sn mode in SnO 2 , which confirms the presence of SnO 2 in the PANI matrix.…”

“…The SEM images of nanocomposite in which the grain is irregular in shape and the SnO 2 oxide partilcles are not well dispersed. According to A. А. Мatnishyan et al [13], the SEM micrographs show high homogeneity of the nano material consisting of homogeneous nanocomposite and a globular particle is produced with inclusion of higher formation of PANI globules with sizes in the range of 30-50 nm.…”

Tin Oxide (SnO 2 ) nanoparticles were prepared by the microwave-assisted solution method. Aniline monomers were prepared and polymerization in the suspension of SnO 2 to form nanocomposites material, in which SnO 2 nanoparticle was embedded within the polyaniline chain (PANI). Structural, Optical, Morphology and AC electrical conductivity studies of the sample were carried out using power X-ray diffraction, Fourier Transform Infrared Spectroscopy, UV-Vis Spectroscopy, Scanning Electron Microscope, High-Resolution Transmission Electron Microscope and AC Impedance Spectroscopy. Powder XRD helped to confirm the formation of PANI/SnO 2 composites and the crystallite size of the nanocomposite is found to be 16 nm. Structural changes of PANI due to the presence of SnO 2 in PANI/SnO 2 nanocomposites have been analyzed in FT-IR and UV-Vis spectrum. SEM images show the morphology of PANI/SnO 2 nanocomposites. HRTEM images were observed and showed that the SnO 2 was scattered and confirmed the PANI chain that formed a PANI/SnO 2 nanocomposites material. AC conductivity was studied in the frequency between 10 Hz -8 MHz. At higher angular frequencies, the nanocomposites exhibit almost the maximum value of AC electrical conductivity (σ ac ) is found at 303K of SnO 2 in PANI.
