Abstract
The current paper deals with investigation of (PANI)1-x(TiO2)x nanocomposites to explore possible material for optoelectronic devices. To investigate the effect of TiO2 concentration on structural, surface morphology and chemical properties of PANI, samples were characterized by XRD, FTIR, SEM and Raman spectroscopy. The XRD pattern evidence the presence of a blend of anatase and rutile phase of TiO2 within the PANI matrix which shows amorphous nature of the matrix. FTIR and Raman spectra confirm the formation of PANI/TiO2 nanocomposites. SEM images show the appearance of lumps into smooth PANI samples with addition of TiO2 nanoparticles. The thermal and dielectric properties were studied using TGA and Impedance analyzer, respectively. The results showed that the addition of TiO2 improves the thermal stability, which clearly shows its potential application in optoelectronic devices.
