Abstract


The structural and optical properties of the PANi films were investigated in terms of different solvent content by using X-ray diffraction (XRD), RAMAN spectroscopy, Scanning electron microscopy (SEM), Photoluminescence (PL) and optical absorption spectroscopy. The XRD results revealed that the crystallinity through films increased as the molar ratio of dimethylacetamide (DMAc and dimethylformamide (DMF) increased to 0.6:0.4, but then decreased when the molar ratio was increased from 0.6:0.4 to 0.8:0.2. It is shown that even small clusters in PANi films can explain the observed RAMAN scattering.  The results of the optical experiments showed that films prepared from different molar ratio of DMAc and DMF showed good near-infrared characteristic in the range of 800-2000 nm. The optical band gap value from absorption coefficient data is found to be 3.57 eV.    The SEM also showed changes in the morphology of PANi films.
