“…The intensity of the peak present at 16.59̊ increases with increase in the Cz concentration confirms copolymerization of indole and carbazole. Similar nature of patterns can be seen in the reports [8,10]. The XRD patterns of Polyindole and Polycarbazole monomer presented in our earlier paper [11,12].…”

“…The most characteristic difference is variation in the intensity of the band at 1051 cm -1 , appeared in the copolymer alone signifies the incorporation of ClO4anions and confirms interaction between indole and carbazole monomers [6]. The band at 741 cm -1 is due to CH bond in the benzene ring of indole [6,10,13]. The band at 812 cm -1 attributed to C-H deformation in tri substituted benzene ring [6,14].…”

The copolymer containing different wt% of indole and carbazole were synthesized by following in situ copolymerization method using ammonium persulfate as oxidizer, at room temperature. Crystalline and amorphous phases were noted from XRD patterns of the samples. Structural and optical studies were carried out by FTIR and UV-Vis spectroscopy. Different functional groups in the prepared copolymer have been identified and optical band gaps were determined to vary from 3.83 eV to 3.96 eV and 3.98 eV to 4.13 eV corresponding to direct and indirect transitions. Dc conductivity measured in the temperature range of 300 K to 423 K is observed to be semiconducting type. Two different regions of variation of conductivity with temperature have been observed and the corresponding activation energy was determined. The increase in conductivity and decrease in activation energy with increase of wt% of Cz content in PInCz copolymer is observed. This may be due to decrease of hopping distance of polarons with increase of Cz contents in the copolymer.

In the present research work, the optical properties of one pot chemically synthesized polypyrrole/poly(vinyl acetate) composite films using FeCl3 as an oxidant have been studied. The result of X-ray diffraction (XRD) analysis depicts the amorphous nature of the prepared composites. The surface morphology of prepared sample was analysed through FE-SEM, which shows granular morphology. The ultraviolet-visible (UV-VIS) spectroscopy was employed to study optical parameters. The composite films exhibited strong absorption below 250 nm with well-defined absorption peak at around 225 nm. The optical band gap values of all prepared samples ranges over 2.876 – 3.843 eV. These obtained values of optical parameters suggested that the prepared materials have the potential applications in optoelectronics devices. Key words: optical properties; polypyrrole/poly(vinyl acetate); composite films.
