Structural, Optical, And Frequency Dependent Conductivity Properties Of PANI/Ceo2 Nanocomposites By In Situ Polymerization Method

Le résumé fourni par la source

This article explain a novel synthesis for producing Polyaniline / CeO 2 nanocomposites with five weight percentage (5wt%) by in situ polymerization technique.The synthesized nanocomposites were analysing using many measurements like X ray diffraction (XRD), absorption UV spectroscopy, FTIR, and impedance spectroscopy.An XRD result tells that the structures of nanocomposites are nanocrystalline.The grain size of the nanocomposites was calculated by XRD analysis, has around 9.8 (nm).The optical studies response for the nanocomposites, shows the possible visible absorption peaks for PANI/CeO 2 nanocomposites in the region of 273, 342, 634 and 872 (nm).Band gap energy of nanocomposites is discussed and calculated, it is 3.3 (eV).The FTIR characterization was analyzed and was confirmed the functional group of the nanocomposites materials.AC Conductivity properties are done and conductivity () at various logarithm frequencies (log f) and various temperature are reported.Hopping of electron between ions is the nice of the nanocomposites and hopping mechanism was discussed.
