In the present communication, Polythiophene/poly(vinyl acetate) (PTh/PVAc) composite thin films were synthesized by chemical oxidative polymerization method in methanol is reported. The prepared composite were characterized through X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), ultraviolet-visible (UV-Vis)spectroscopy and photoluminescence (PL) measurement. The broad peak was displayed in the PL spectra for the preparedcomposite at around 390 nm, proposed prodigious charge generation efficiency. The analysis of the optical parameters of theprepared composite was carried out by spectral analysis using a UV-Vis spectrophotometer. The obtained results, whichwere as follows: energy band gap of 4.58–5.31 eV, complex refractive index coefficient values of 1.175–1.193 and opticalconductivity values in the range of 2.58×108–5.24×108 S.cm-1 at 270 nm. The above results shows the studied compositefilms are expected to offer potential applications in optoelectronic devices.

Abstract


In the present communication, Polythiophene/poly(vinyl acetate) (PTh/PVAc) composite thin films were synthesized by chemical oxidative polymerization method in methanol is reported. The prepared composite were characterized through X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), ultraviolet-visible (UV-Vis)spectroscopy and photoluminescence (PL) measurement. The broad peak was displayed in the PL spectra for the preparedcomposite at around 390 nm, proposed prodigious charge generation efficiency. The analysis of the optical parameters of theprepared composite was carried out by spectral analysis using a UV-Vis spectrophotometer. The obtained results, whichwere as follows: energy band gap of 4.58–5.31 eV, complex refractive index coefficient values of 1.175–1.193 and opticalconductivity values in the range of 2.58×108–5.24×108 S.cm-1 at 270 nm. The above results shows the studied compositefilms are expected to offer potential applications in optoelectronic devices.
